< Back Blending Annuals and Perennials for Continuous Summer Bloom Gardens built on perennials alone can shine brilliantly for a few weeks, then settle into quieter stretches. The solution isn’t to abandon perennials, but to partner them with annuals in a way that keeps the show going from late spring to frost. By layering the strengths of both—perennials for structure and rhythm, annuals for reliable, season-long color—you can create a garden that never feels finished but never feels empty either.

Some peak in late spring, others in midsummer, and a final group carries into fall. Even the longest-blooming perennials have natural pauses. Annuals, on the other hand, are marathon performers. Once planted, they flower continuously until frost, largely indifferent to the seasonal ebb and flow around them. When you design with both in mind, you create a relay: as one plant finishes its moment, another seamlessly takes over. Color with Intention A successful mixed planting doesn’t rely on randomness. Start with a defined color palette—whether it’s soft pastels, vibrant contrasts, or a relaxed cottage mix—and repeat those colors throughout the space. Don’t overlook foliage. Silvery leaves, chartreuse highlights, and deep burgundy tones provide continuity even when flowers ebb, acting as a visual thread that ties the garden. Cherry Wave petunias and rudbeckia daisies; Credit Julie Deane Designing for a Natural Look The most effective mixed plantings avoid rigid patterns. Instead of isolating annuals in separate beds, tuck them into open pockets among perennials. This interplanting creates a cohesive, layered look and prevents the garden from feeling segmented. And always plant with growth in mind. What looks sparse in early spring will fill in quickly. Leave space for air circulation and mature size—your plants will reward you with better health and stronger performance. Maintaining the Momentum A continuous display does require a bit of attention. Deadheading encourages many annuals—and some perennials—to keep blooming. Or choose plants that don’t require deadheading, like wave petunias and rudbeckia daisies in the pictures. Regular fertilizing supports the heavy flowering demands of annuals, which tend to need more nutrients than their perennial counterparts. Consistent watering, especially in mixed beds, ensures neither group is stressed during hot weather. By midseason, don’t hesitate to edit. Remove plants that are past their prime and replace them with fresh annuals. This simple refresh can extend the garden’s vibrancy well into fall. garden of mixed perennials and annuals; Credit: www.storage.googleapis.com Stretching Your Budget A beautiful garden doesn’t have to be an expensive one. Invest in high-quality, reliable perennials—they’ll form the backbone of your design for years to come. Annuals, meanwhile, can often be grown from seed at a fraction of the cost, offering abundant color for minimal investment. Some will even self-seed, returning unexpectedly in future seasons and adding to the garden’s evolving character. Dividing established perennials is another easy way to expand your planting over time, filling more space without additional cost. phlox seedling; Credit: www.sowrightseeds.com Designing for Continuity A garden designed for continuous color isn’t about achieving a single perfect moment. It’s about creating a sequence—one that unfolds gradually, shifts with the season, and remains engaging from beginning to end. When annuals and perennials are thoughtfully combined, the garden becomes less about peaks and pauses, and more about flow. And that’s where the real beauty lies—not in perfection, but in continuity.

< Back Buttonbush (Queen of the Wetlands) Jim Lakin, M.D., Master Gardener Buttonbush is a great shrub for naturalizing in wet areas and attracts butterflies. Read more about its attributes. We have some wonderful marsh lands on our property. Among the Giant Blue Lobelias and the Cardinal flowers, there’s a delightful shrub that stands out, the Buttonbush ( Cephalanthus occidentalis ). This is a native perennial plant to much of the Eastern North America from Nova Scotia to Minnesota, south to Florida and East Texas. You’ll find it in a range of wetland habitats including swamps, floodplains, mangroves, around ponds and margins of streams and even moist forest understories. It grows as a deciduous shrub or small tree, running from three to ten feet in height. It has glossy green leaves which appear in the late spring. Its unique fragrant white to pink bloom, shown in the first picture, gives it its common name. Buttonbush usually blooms from June through September although this period may be shorter further north. It was introduced commercially in 1735 as a source of nectar for commercial honey production. Thus, it’s other common name, Honey Bells. Buttonbush forms an important link in the wetland ecology. A number of waterfowl eat the seeds and wood ducks use the plant as nest protection. We’ve had a pair in our pond for several years that seem to regularly avail themselves of our buttonbushes building material. Deer browse the foliage which surprisingly is poisonous to livestock. Darn deer eat anything! A number of native as well as honey bees feed on the nectar as do hummingbirds. The plant acts as larval host to Titan Sphinx, Walnut and Hydrangea Sphinx moths. It can be used in butterfly gardens, as a naturalizing plant or to control erosion in difficult, moist areas. It’s great for naturalizing. To grow Buttonbush, select a fairly moist environment. As you might imagine it has a pretty high water requirement even though it likes shade to part shade. It is a spreading multi-branched shrub with an irregular crown which produces balls of white flowers resembling pincushions. As it can get a bit lanky, plants in a more formal setting might need to be pruned from time to time. It is a rapid grower and spreads by suckering. It is said to be hardy from Zones 5 to 11 although a number of plants do just fine in Zone 4. For Minnesota gardeners it might be wise to consider planting in a protected area and mulching in the fall at least for the first year or two. Getting a local specimen is also important. Buttonbush is an otherwise hardy ornamental perennial. It’s a native that is an attractive addition to any moist shady area. Photo credits: Jim Evans, Wikimedia Commons (1), C.

< Back Pagoda Dogwood (Cornus alternifolia) Jim Lakin MD, Master Gardener Looking for a small tree to add to your landscape? Consider the Pagoda Dogwood, it grows quickly and offers delicious berries for the birds in late summer. Read more about this attractive tree here. January is a time for planning. Where to put the annuals can be figured out on the fly. Perennial forbs take a bit of thought but you can dig most of them up if you want to move them next year. However, tree placement should be very carefully considered. What looks good now will be there years from now and may not look so good. Short of a chainsaw massacre, you’ll be stuck with the ill-considered tree. Then, of course, you have to consider size. Do you really want a 90-foot white oak in your 12 x 16 courtyard? Fortunately, if you are looking for a small tree, you have many excellent choices, one of which is the Pagoda dogwood (Cornus alternifolia) or alternate-leaved dogwood. This beauty is a common understory tree which grows rapidly as a youngster, adding a new tier of branches each season. Pagoda dogwood is native to northeastern North America and is found in central and southern Minnesota, Iowa and all the way down to the Ozarks. It does best in well-drained soils and will have difficulty in clay or compacted soils. In the wild it is found in moist woodlands so it is best to plant it where it is protected from the hot afternoon sun. Observing this caveat, it will grow in full sun if there is sufficient moisture, but it will do better in part to near-full shade. One of its most compelling features is the berries produced in late summer, greatly loved by the birds. For good fruit-set, however two separate trees are needed. After a time, some trunks will suddenly die and turn orange. Quick rejuvenation is possible by pruning away the dead trunk. Select a vigorous new shoot from the sprouts that usually emerge quickly. Pagoda dogwood’s horizontal tiers of branches give the tree its name and render it a charming ornamental at the corner of the house or the edger of a wooded landscape. It is great as a bird garden plant. These lovely branches are festooned with clusters of creamy white blooms in the late spring. The resulting berries are bluish black and ripen in late summer, providing welcome nourishment to a variety of songbirds. Come fall, the leaves will turn a striking yellow to burgundy. The popularity of this showy ornamental has been enhanced by the development of a number of great cultivars. You might check your local nursery this spring for such attractive varieties as “Pistachio”, “French Vanilla”, “Gold Bullion” or “Big Chocolate Chip”. Whichever you choose, keep it well-watered and mulched that first year and you’ll soon have a great addition to your landscape!

< Back A Rapid Growing Native Shade Tree: The Birch (Betula spp.) Jim Lakin MD, Dakota County Master Gardener The birch tree is so much a part of Americana and so dear to the hearts of all Northern Midwesterners, it’s a pretty easy sell to suggest adding some to your landscape. But, hold on, there are facts to understand about various types of birch to ensure that the one that you choose will thrive in your yard. This article focuses on three types of birch that are commonly used in Minnesota. So was I once myself a swinger of birches. And so I dream of going back to be. It’s when I’m weary of considerations, And life is too much like a pathless wood… From Birches by Robert Frost The birch tree is so much a part of Americana and so dear to the hearts of all Northern Midwesterners, it’s a pretty easy sell to suggest adding some to your landscape. Mind, this is a full-sized tree and one that will send out roots from which spring a gathering of birches if left to their own devices. In other words, it probably is not a suitable planting for a small suburban lot. If you do have a bit of room, however, within a few years you can achieve a gorgeous stand of grey-white sentinels, rustling softly in the summer wind, gently presiding over the restrained winter landscape. About seventeen species of birch are native to North America. They are rapid growing, reaching as much as 80 feet in height with a spread about half the height. Birches tend to colonize open ground, especially after a fire or other disturbance. In general, they favor light, well-drained, acidic soils as are often seen as pioneer trees after a burn. Of these seventeen, three species are most often used for landscaping: Yellow birch, River birch and Paper birch. Yellow birch ( Betula alleghaniensis ) is found across the Great Lakes into Minnesota. It is easy to grow from seed and transplants well as is true of all three species. It makes a fine shade tree but should be planted in a moist, sheltered site. So, an area to the north or east of the house would be ideal. Once established, the trunk and limbs display a shimmering silvery to copper gray exfoliating bark. Try crushing the buds or stems. They give off a strong scent of wintergreen! River birch ( Betula nigra ) as the name implies is mostly confined to the flood plains and riverbanks of the Midwest. The lower Minnesota River is a great place to look for them. Unlike its sisters, it is primarily a southern Midwestern tree, cold-hardy up to USDA zone 4. Also, it is susceptible to highly alkaline soils. So, keep plantings away from streets and sidewalks with alkaline concrete deposits. It’s not a street tree. It looks great in clumps developing a charcoal grey trunk over time. The younger bark is an attractive exfoliating white, with cream to salmon shades underneath. Paper birch ( Betula papyrifera ) is greatly prized for its stunning white bark. It prefers the cooler Upper Midwest. Unfortunately, many have fallen to the bronze birch borer. Borer-resistant strains have been developed and should be sought in your local nursery. Paper birch requires full sun and requires well drained soil. It makes a dramatic mass planting on the edge of woodlands, its native niche. So, take your pick, depending on your situation. But a word of caution: don’t swing on them. As Robert Frost once admitted, “It was almost sacrilegious, climbing a birch tree till it bent, till it gave and swopped to the ground, but that’s what boys did in those days”.

< Back Pruning Hydrangeas and Clematis Carolyn Plank, Master Gardener Ever wonder when is the best time to prune hydrangeas and clematis? This article will help clear up the pruning mystery for these beautiful blooming plants. Ever wonder when is the best time to prune hydrangeas and clematis? In this article I’ll help clear up the pruning mystery for these beautiful blooming plants. HYDRANGEAS When to prune hydrangeas depends on when it blooms. If the hydrangea blooms in late summer on new growth, pruning should take place in late winter or early spring before the shrub begins active growth. Some of the hydrangeas in this category include Limelight, Burgundy Lace and classic snowball types. Most other hydrangeas that bloom on old wood (growth from the previous year) should be pruned in summer after they’re done blooming. Pruning too soon increases the risk of cutting off dormant buds. Oakleaf, Big Leaf, Nikko Blue and other pink and blue flowering hydrangeas bloom from the previous year’s buds. If you want to maintain their size or shape, prune in summer before August. Ever-blooming hydrangeas such as Endless Summer also bloom on old and new wood and should also be pruned the same way. CLEMATIS Clematis pruning made simple. There are three groups of clematis. Group I is in the Red Category (red means stop) and blooms in early spring set on old wood from the previous year’s wood and doesn’t die back in winter. Pruning should be done sparingly. This category includes Pink Perfection, Spooneri and Pink Swing. Group II is in the Yellow Category (yellow means go slow) and grows on old wood in late spring/early summer, and on new wood in late summer or fall. This group should be given a light trim in March before it begins blooming. Remove dead wood and cut back remaining stems to 6-8”. This category includes Horn of Plenty, Patricia Ann Fretwell and Beautiful Bride. Group III is in the green category (green means go) and blooms on new wood in summer and dies off to the ground over winter. In March, prune all stems back to a strong set of buds 12” from the ground. This category includes Summer Snow, Prince William and Mississippi River. Stems of live and dead wood look alike. The leafy growth from the bud indicates a live vine. Always prune from the top down. Work down each vine until you find a live bud or growth and then stop once you find it. You can cut off all of last season’s growth to the ground; however, this results in a shorter plant, a few less flowers, and will bloom a little later. Happy pruning!!

< Back Imagining Your Garden’s Possibilities January is a month of fresh starts, a time to renew and begin again. Whether you were pleased or frustrated with your garden in 2021, the new year is a great time to dream about your 2022 garden’s possibilities. Valerie Rogotzke shares some thoughts about how to reimagine your garden. Valerie Rogotzke, Master Gardener January is a month of fresh starts, a time to renew and begin again. This might not seem to be the best time to be thinking about the garden for Minnesotans, but the frozen ground outside gives gardeners a reprieve from weeding and a chance to imagine possibilities for the future. Perhaps your dream garden evokes a specific place. Imagine an English cottage garden with meandering borders bursting with colorful perennials and a bench under an arbor of hardy wisteria, like one of Gertrude Jekyll’s horticultural masterpieces at Hestercombe House or Lindisfarne Castle . Picture a formal French garden with manicured hedges and a water fountain, like the grounds of Vaux-le-Vicomte or the Tuileries in Paris. Envision a Japanese garden such as Kenroku-en or Koraku-en with winding stone paths through mossy undergrowth, evergreens in abundance, and a pool of still water. Which small elements from these styles could be transplanted to Dakota County? Perhaps your dream garden serves a particular function, providing you with flowers for cuttings, bees for pollinating, or vegetables for eating. To have flowers for bouquets all through the growing season, gardeners must plant with an eye to the calendar, making sure there are options peaking in each month. In addition, it is helpful to have flowers of different scales when assembling arrangements, with larger blooms like dahlias and roses balanced by smaller blooms or ornamental grasses to fill the vase. To encourage bee populations, begin to dig around in the UMN Extension program’s resources on choosing the best pollinator-friendly plants for our area and creating habitat and nesting sites for pollinators. To maximize your success with vegetables and fruits in your garden, take some time now, in winter, to take stock of what has been growing in your garden and what you would like to cultivate this year. Perhaps you have always wanted a small plot of asparagus or a pizza garden with basil and tomatoes. Maybe it’s just time to try something new: sorrel, maybe, or endives? Browse the U’s vegetable guides for ideas and tips for healthy vegetables. A vegetable garden need not be a grand ornamental potager like the kitchen gardens of Villandry – just consider what things you want to eat. Perhaps your dream garden includes time-intensive projects that will not be ready in a year or two, like espaliered apple trees . Perhaps you’d like to rewild an area of your land to encourage native prairie growth , build an Elizabethan knot garden out of interlocking hedges, or develop a natural dye garden with madder and indigo and coreopsis in order to dye fabrics. Whatever your dreams are for your garden, do your dreaming now and dream big! There will be time to prune these dreams back later when practical concerns are considered but January belongs to the imagination. Photo credits: University of Minnesota Extension (1, 2, 3)

< Back American Holly (Ilex opaca): Deck the Halls! Jim Lakin MD, Dakota County Master Gardener American holly is a tree that breathes festivity! In winter’s white silence, American holly radiates merriment showing red berries on olive green leaves. Boughs often find their way into Christmas wreathes. But this tree is also a great year-round addition to the landscape. Read this article to learn why. It may be August but I’m getting stoked up for the Holidays, thinking about American holly ( Ilex opaca ), a tree that breathes festivity! In winter’s white silence, American holly radiates merriment showing red berries on olive green leaves. Boughs often find their way into Christmas wreathes although this tree is a great year-round addition to the landscape. American holly grows to a height of 15 to 30 feet. Native to the Eastern Coast and nearer Midwest, northern cultivars have spread across Iowa and up into Southern to Central Minnesota. When purchasing American Holly, do be careful to select a cultivar that has proven its hardiness in the Midwest. If you have any questions about that, you might consult the website of the Dawes Arboretum in Columbus, Ohio. They have an excellent collection of over 200 cultivars adapted to the Midwest. Mature American holly When selecting your specimen, you must be mindful that American Holly is dioecious. In other words, there are boy trees and girl trees. So, a male tree must be in the neighborhood for female trees to produce fruit. There are a number of hybrids available commercially. They do grow more rapidly than the native variety. However, they are far less hardy. A severe Minnesota winter can reduce their leaves to a dingy brown, not so festive for Christmas. If you are patient, the native cultivars will slowly grow and demonstrate remarkable hardiness. A few points for siting should be kept in mind. American holly is hardy only to Zone 5. So, in Minnesota it is best to select a protected site from the winter winds. Also, it requires full sun to part shade to thrive. Our hot summers can also affect the tree, so it’s best to site is where it enjoys the afternoon shade. Well-drained soil is a must. It does best in a neutral to acid soil, so amendments should be made if your soil is alkaline. fruit of the female tree If care is taken and patience exercised, American holly will provide great rewards. This stately and colorful tree will bring joy and lift the spirits for many a Holiday Season. Photo Credit: Missouri Botanical Garden (1,2)

< Back Disruption to Delight: Partnering with the City to Start a Bee Lawn Pat Peschman, Dakota County Master Gardener Are you interested in doing more to help our native pollinators? If so, consider turn all or part of your lawn into a bee lawn. A bee lawn can provide a recreational space for you and it can also provide much-needed food resources for bees and other beneficial pollinators. This article describes Master Gardener Pat Peschman’s experience with developing a bee lawn in her yard and includes some excellent advice. In 2024, my husband John and I received a dreaded letter announcing summer-long infrastructure and road maintenance that would impact our property. Initially, we only recognized the losses—our boulevard native garden had to move, our driveway would be torn up, and trees would be removed. However, my husband recognized an opportunity. We had discussed converting part of our lawn to a "bee lawn," to create habitat for pollinators. John developed a relationship with the project manager for the construction, and through this partnership, our new bee lawn became a reality. Benefits of a Bee Lawn A bee lawn is a combination of turf grass and flowering plants. It is low-growing, allowing it to replace a traditional lawn while maintaining a manicured appearance and tolerating some foot traffic. Bee lawns offer several advantages over turf lawns including: Pollinator Support: Flowering plants provide nectar and pollen throughout the growing season. Low Input: Requires less water, fertilizer, and herbicides. Low Maintenance: Requires less mowing. (My husband only mowed our bee lawn twice the first year!) While bee lawns should not be our only approach to feeding pollinators, they can be a piece of the puzzle. 1. Location and Site Prep Select a site with well-drained soil that receives full to part sun (at least 3-6 hours of direct sun per day). Avoid heavily trafficked areas to prevent soil compaction. The site will need to be prepared to receive and support the seed. The "Construction" Method: We had a unique advantage because the city tore up the lower third of our lawn. Instead of resodding, they collaborated with us to create spaces for the bee lawn, bringing in clean black dirt and even watering the area. The DIY Method: If you do not have construction assistance: Ideally, remove the lawn with a sod cutter or rototiller. If weed pressure is high, solarize the area by applying clear plastic for several weeks. At a minimum, cut existing lawn very short and rake heavily to expose the soil. layout of bee lawn 2. The Seed Mix Bee lawn seed is a combination of cool-season turf grass, particularly fine fescues, and flower seeds. Kentucky bluegrass will work as well but requires more input. Recommended flower species include: Dutch White Clover Self-heal Creeping Thyme Note: These mixes are commercially available at many garden centers or through companies that support or install bee lawns. Self-Heal and White Clover 3. Seeding Timeline Late Fall (Ideal): Also known as "dormant seeding" (early Nov to mid-Dec). Spread seed evenly over prepared soil, a seed spreader works well. Winter weather works the seed into the ground, and minimal watering is required. Spring: Wait until mid-May (after frost danger). Lightly rake the seed into the soil. This requires frequent watering (lightly, 2-3 times per day) until germination. In both seasons, apply a light straw cover so birds do not eat your seed. 4. Maintenance and Care Watering: Once established, only water during prolonged drought. Fertilizing: Dutch white clover fixes nitrogen in the soil, so fertilization is rarely needed. Mowing: Wait until the lawn is 5–6 inches high, avoid mowing when the lawn is flowering. Only remove the top one-third of the plants. Leave the clippings on the lawn. Mow in late fall to prep the lawn for winter. Weeding: some hand weeding may be required the first season bee lawn flowers and ruler measuring height A Buzzing Success Since establishing our bee lawn, countless individuals walking past our property have stopped to inquire about the lawn and offer compliments. We have definitely seen our lawn abuzz with pollinators. This year’s goal is to try to count and identify our visitors!

< Back Square Foot Gardening Do you want to grow vegetables in your garden but you don’t have a lot of space or you only have one sunny spot or your soil isn’t conducive to growing or you just want a few vegetables for your family? Square foot gardening may be your answer. This approach will save time, work, space, and water. And, you will produce some delicious vegetables for your family. Read this article for more information about why square foot gardening may be for you and how to get started. Mickey Scullard, Dakota County Master Gardener With a short growing season, gardeners want high yields of fresh produce from their vegetable gardens, yet many people have limited space suitable for growing. “Square Foot Gardening” is a method of gardening with the underlying premise of producing a greater variety of vegetables in a small space. It is also intended to make gardening more accessible to a greater number of people. According to the Square Foot Gardening Foundation website , this method is, “estimated to cost 50% less, use 20% less space, 10% of the water, and 2% of the work”. They state there will be almost no weeds and you save time and effort because you don’t have to dig, rototill, or use heavy equipment, and fertilizers aren’t needed. It almost sounds too good to be true! However, many people have used this method successfully for 25 years. In the U.S., our standard gardening approach is to plant in rows. This is how many of us have done it for generations, passed down through our families. We have developed tools that support this approach for watering and weeding between the rows, using mulch papers or rototillers small enough for a row. We have row markers, seed tapes, and many other gardening supplies that support the row gardening approach. According to Bartholomew, this approach makes gardening harder than it needs to be with much of the growing space given over to aisles between the plants, resulting in a need to constantly weed those non-growing areas. He also argues that planting in rows results in overplanting. He uses the example of planting cabbages, suggesting few people find it useful to have 30 cabbage heads ripening at the same time. Square foot gardening suggests a different approach that carefully spaces plants to efficiently use space, manage the size of the harvest, and allow for successive planting, e.g., growing multiple crops in one growing season. Instead of sowing seeds and then having to thin the plants, this approach suggests placing the seeds at the distance you’d thin the plants. For example, if the seed packet says thin to 6 inches between plants, you can just space your seeds out that distance in all directions within the square. You can put a ‘pinch’ of seeds in each planting site to increase the chances of germination and instead of thinning, snip out the unneeded plants. This lessens the chance of disturbing or weaking the roots of the plant you are keeping. Most square foot gardens are 4 feet x 4 feet raised beds. They can be other sizes; however, you will want to make sure you can reach all areas of the bed without stepping on the soil. Stepping on soil compacts it, which makes it more difficult for plants to grow. The soil in the raised bed should be a mix of compost, vermiculite, and peat moss. The location of the square foot garden is important, with sufficient sunlight important and access to a water source. Bartholomew suggests placing it near the house so you always have a visual on your growing plants. Within the 4 x 4 space (or whatever size bed being used), a grid of 1 foot x 1 foot squares are laid to mark out each plot. In a 4 x 4 bed, you will have 16 squares in which to plant. The number of plants or seeds you grow in each square is dependent on the full size of the vegetable or flower. For example, in the 1 ft x 1 ft square, you could grow one tomato, or four heads of lettuce, or eight bunches of swiss chard, or sixteen carrots, or thirty-two radishes. Once you have harvested the vegetable, a new crop can be planted. Since one of the other premises of Square Foot Gardening is reducing the need for fertilizer, Bartholomew says you only need to add a shovel of compost prior to each new planting. Square foot gardening will meet the needs of many gardeners. However, those wanting to produce large harvests for canning, freezing, and other methods of preserving, may not find they get the quantities they want using this method. For those wanting a manageable amount of produce, this may be a great way to help limit the amount grown, although if you grow a zucchini plant, you will probably still need to sneak around after dark ‘bestowing’ your bounty on your neighbors’ doorsteps.

< Back Shrubs With Fall Fireworks Mary Gadek, Dakota County Master Gardener As the crisp air of autumn settles over Minnesota, the landscape transforms into a vibrant canvas of fiery reds, golden yellows, and deep oranges. While the towering maples and oaks often steal the spotlight, a stunning variety of fall color shrubs add rich layers and texture to the seasonal display. From the brilliant red foliage of the red chokeberry to deep purple leaves of the Flaviramea yellow stem dogwood, these hardy shrubs not only thrive in Minnesota’s climate but also bring dramatic fireworks of color to gardens, parks, and natural areas. Their dazzling hues and low-maintenance nature make them a must-have for anyone looking to extend the beauty of fall well into the season. Read this article to see which shrubs shine bright in the fall. Cause of color change in fall leaves: Fall color in leaves is driven by three pigments: chlorophyll, carotenoids and anthocyanins. Chlorophyll, the green pigment, is crucial for photosynthesis during the growing season. In the fall, the day length shortens and temperatures cool, which triggers plants to prepare for winter by reducing chlorophyll production. When chlorophyll production stops, the green color fades, revealing the yellow and orange hues of carotenoids. Also, anthocyanins, which give red and purple colors, are produced in late summer and early fall as photosynthesis slows down. Environmental factors, like warm days and cool nights enhance anthocyanin production, leading to vibrant colors. Not every shrub species produces carotenoids or anthocyanins in equal quantities. This is what creates the difference in fall color from species to species: Intensity and duration of leaf color varies with each season : Weather conditions in early fall largely determine the intensity and duration of leaf color. The best fall color shows when days in early fall are sunny and mild, and nights are cool but remain above freezing. Long periods of cloudy, rainy weather or a hard freeze in early fall will mute fall colors. Obtaining a fall shrub fireworks display : Continue to show off your beautiful garden in the fall, after the summer blooms have disappeared, with some of these shrubs: Limelight Hydrangea Chokeberry: Black chokeberry, like the "Viking" variety, yields spectacular, bright red autumn foliage and is known for less suckering, compact growth and large berries after white spring flowers. Note: The chokeberry is considered a good substitute to the burning bush, which is now considered a restrictive noxious weed in Minnesota. https://extension.umn.edu/identify-invasive-species/burning-bush Redosier Dogwood: The versatile, fast-growing dogwood reveals bright red or yellow stems as the season progresses. Some varieties, like the 'Flaviramea', bring red-purple fall foliage, too. Hydrangea: Choose from many Minnesota hardy hydrangea shrubs that explode with enthusiasm in the summer months and, then, grant us all an encore of mauves, greens and golden-brown flower heads in the fall. ‘Limelight' hydrangea starts with a lime-colored summer display and ends with deep pink as it ages. Staghorn Sumac: This native shrub exhibits bright reds and oranges in the fall and works well in a larger area. ‘Tiger-eyes’ sumac is a smaller selection of staghorn sumac, requiring less space in your garden. It boasts chartreuse green foliage in the spring, yellow foliage during the summer and fiery orange foliage in the fall.

Lavender (Lavandula Angustifolia) is a cutting gardener’s favorite that combines function and beauty. The distinctive fragrance and attractive foliage make lavender a companion plant for a rose garden by covering the lower rosebush canes. Essential oils are said to revive the spirits and fragrant blooms are said to have a calming effect. It has been a difficult plant to grow in zone 4 despite the alkaline soil that lavender prefers. Lavender often died in Minnesota until new research from the Chicago Botanic Garden Plant Trials (2017) showed which varieties are hardy in their USDA Zone 5 conditions. Based on an evaluation process the following seven types are hardy in zones 4 and 5: Imperial Gem, Royal Velvet, Munstead, Super Blue, Jean Davis, Niko, and Sharon Roberts. With a winter mulch of chopped leaves plus some topsoil, to keep the leaves in place, gardeners in the Twin Cities metro area have been successful with the Munstead variety. Ideally 2 feet of snow will protect the plant, also. Growing lavender in this area requires full sun, and well-drained soil—gravelly or sandy soils are ideal. Growers should plant early in the spring to allow for the longest growing season. Maintenance needs are few since lavenders do not need irrigation or fertilizer. Deadheading is the gardener’s choice but it will keep the plant neat looking. Cut the plant back one-third after blooming. Do not cut back to the ground in the fall. The gardener may need to trim the branches in the spring for reshaping. Natural oils of the lavender plant repel most grazing animals such as deer and rabbits. The fragrant blooms may be harvested and dried to make fragrant lavender pockets for sweaters or the lingerie drawer. Other uses include baking, teas, a drop in an infuser, or drop on a pillowcase to improve sleep quality. References Chevallier, Andrew. Herbal Remedies. Easy-to-Use Visual Reference Guide.

< Back Therapeutic Landscapes for Stress Relief Feeling stressed? Has the Covid culture left you feeling socially isolated? Learn about the healing power of gardens and gardening in this article. Cathy Johnson, Master Gardener The notion that gardens are healing places is not new. It is well supported in research that outside settings improve mental and physical health . . . improved focus, improved creativity, reduced depression and stress, shortened hospital stays and increased test scores in classrooms where plants are growing. One only has to look at the Minnesota Landscape Arboretum’s Nature Heals Toolkit to see the profound connection between nature and healing. After all, folks are Covid weary beyond belief and wondering - is there some end in sight for the recurring surges and resulting restrictive lifestyle which seems to be the new norm? Peter Petrow of the Washington Post wrote an article, ‘Embracing Healing Places,’ which led me to thinking about how therapeutic landscapes might just be even more healing now than ever. After all, humans are “biophilic” - innately drawn to life - because we are genetically connected to plants and nature. Being in nature makes our brains secure, more connected to what our bodies are experiencing. But the Covid pandemic resulted in more of us working indoors, some seldom having to leave our places of residence. We have become used to using our computers to shop and having items delivered, reducing the need to go outside. Social isolation can only increase feelings of disconnect, and a longing for things to “get back to normal.” Geraldine Perriam, a professor at the University of Glasgow, states that humans, while on a quest for healing, seek not just a cure, but alleviation and improvement in life style. The question for individuals then becomes, ‘Where do you need to go to for healing? What places make you feel better. The answer will be different for everyone, but a few common threads emerge from research, which are helpful to us all. Water is the most common element listed in descriptions of healing places. The colors of blue and green are associated with calm, positive energy and better health outcomes. The obvious connection between the life-giving properties plants and water, comes to mind. On a quest for a feeling of well-being, columnist Pagan Kennedy suggests just going someplace where you can work the soil with your hands. Why? M. Vaccae , a soil bacterium, acts like an anti-depressant once it enters the human body. David Conradson, professor at the University of Canterbury New Zealand, suggests that folks go wherever they feel connected to nature. Are your senses being stimulated . . . all five of them? Sensory stimulation is essential to achieving balance and a sense of ease. In these Covid weary times, humans want to feel “put together again.” Gardening is an authentic experience which provides all of the elements which humans seek in that quest for alleviation, a path toward healing. In imagining your “therapeutic landscape,” remember to think about where you need to go to feel better and be intentional about recognizing those feelings. Look at a map and find green or blue spaces, walk in your yard, or a neighborhood park. Go out of your way to seek your healing place. As for me, I think I’m headed for a garden with some green and blue, some trickling water, some fragrances, warmth, humidity, and just a place to unwind. Maybe I’ll see you there. Hygge on!
