The ideal garden is a showcase every day of the year, highlighting the best of spring, summer, fall, and even winter. The first step is to work with seasonal conditions, not against them.

Spring is an exciting time when existing perennials burst to life and is one of the easiest seasons to plant for newbie gardeners because of April showers and its gentle, nurturing temperatures. Summer brings heat and more watering; one can plant container plants to fill bare spots or for fall color, but transplanting will cause plants distress from which they may not recover. Fall is also the time to plant bulbs that need to overwinter to bloom in the spring. Most gardeners hibernate during winter, but with a little planning, everyone can enjoy looking out the window to see pops of reds, yellows, whites, pinks, and blues year-round.

Basics for Becoming Your Own Landscape Designer

As with any garden project, it all starts with the planning. In this case, it’s important to not only plan for the current season but also to consider what should be planted now that will bloom in the following season. This is even more relevant in the spring, when the gardener’s focus should be on early spring bloomers and late spring bloomers (more on that in a minute), as well as some flowers that will bloom over the summer that can be planted now to become established before the temperatures rise into the red.
Choosing plants can quickly go from an exciting process to an overwhelming experience. The key is to start with aesthetics, as this will narrow down the selection considerably. Select a color—or two or three garden colors—and then check out Canva’s online color wheel for complementary, contrasting, and other harmonious color schemes.

The next consideration is mature plant height. For a seamless transition, you can’t go wrong with taller plants in the back and shorter ones in the front. Opting for perennials in hard-to-reach areas is another good idea.

Grouped plants look better than single flowers. Unless there’s a particularly large plant, plan to plant in odd numbers of three, five, seven, nine, and so on so they look more natural. Even numbers of plants are acceptable when one is planting a long ribbon of flowing color. Follow the spacing requirements of each plant so that they fill in when mature but don’t smother each other.

Incorporate existing landscape features, such as trees and fountains, into the plan; they’re an opportunity to change heights and colors and add a bit of pop to a flowerbed. Depending on their location in the yard, these landscape features can also act as a completely separate focal point to create a vibrant oasis.

Another consideration is staggered bloom times to keep your garden lush and interesting. The Missouri Botanical Garden has a wonderful Plant Finder search that provides the all-important bloom times for a wide variety of flowers, as well as the best growing zones, height, spread, bloom time, sun requirements, water requirements, and more.
Drive around the neighborhood to get ideas from neighbors’ gardens and to see what’s growing well in your local micro-climate. Found a plant you like? Snap a photo and run it through the Google Lens app, which is free, unlike some of the better plant-finder searches. Then sketch it out on paper, or better yet, lay it out on a computer screen.
There’s a reason that landscape designers use plant-planning software; it’s easy, fun, and saves the time that would normally be spent looking up mature plant sizes. It’s easy—simply drag the plant icon into the flower bed. Garden Puzzle features hundreds of flowers and other plants, and even hardscape items such as gazebos, so a homeowner can see the complete final design—and more importantly, make any necessary changes—before the first hole is dug. Best of all, it offers a free trial.

Here are some ideas, by season, to inspire your plans.

Spring Fling

Perennials and bulbs are the backbone of any flower garden, with some perennials such as daylily, peony, iris, New England aster, agapanthus, and heliopsis (false sunflower) able to live as long as 16 years with proper care.

Shake off the winter blues with early spring bloomers such as crocus, pansy, daffodil, Virginia bluebells, snowdrop, winter aconite, claytonia, pasqueflower, marsh marigold (not the one that you’re thinking of), puschkinia, grape hyacinth, hellebore, yellow trillium celandine poppy, Dutchman’s breeches (gotta love that name!), Grecian windflower, and some varieties of tulip.

Annuals have their place, as well, for their unique colors, scents, and textures, and to fill bare spaces where bulbs didn’t come up, or when the perennials are having an “off” year, or when you’re waiting for summer-blooming bulbs such as dahlias, lilies, and begonias to come up later. Violas, snapdragons, African daisy, and biennial dianthus (pinks or sweet Williams), are all colorful cool-weather bloomers.

Now is also the time to plant summer-blooming perennials such as clematis, creeping fox, and perennial dianthus (such as carnations) if they aren’t already in the garden.

Summer Sizzle

Sun-worshipping perennials that can withstand summer heat, such as evening primrose, hollyhock, perennial black-eyed Susans, and lavender, are blooming, and the watering can is in hand. To extend the season beyond mid-summer, consider some annuals, such as zinnia that with proper deadheading (removing dying flowers) will continue to bloom in the fall.

Other hearty choices include coneflower (Echinacea—yes, like the tea), cosmos, dahlia, annual black-eyed Susans, sunflower, bee balm, hyssop, autumn clematis, yarrow, catmint, flowering sage, and Autumn Joy stonecrop.

Got some space in the shade? Consider lobelia, yellow corydalis, and hosta.

Fabulous Fall

The lush red, yellow, purple, and orange of chrysanthemums are the colors of fall. So, too, are the cheerful faces of Marguerite daisies, petunias, phlox, strawflower, salvia, sweet alyssum, verbena, Japanese anemone, and Russian sage. Here’s an interesting tidbit: Most of these flowers are grown as annuals, except in zones seven through 11, where some can be grown as perennials; check the seed packet or with a local nursery.
Shrubs are another way to extend the season, with reblooming azalea, bluebeard, butterfly bush, panicle hydrangea, roses, and rose mallow being top choices for cool to cold climates.

Temperate Climes

Those lucky gardeners whose late fall, winter, and early spring are filled with mild days and cool nights can use cold-season bedding plants that put on a display in temps as low as 20 degrees, or in some cases, even into the teens, and then fade out as spring temperatures rise. Be sure to plant them where they'll receive at least six hours of sun.

Pansies, sweet peas, alyssum, bachelor’s button, calendula, delphinium, dianthus, dusty miller, English daisy, forget-me-not, foxglove, geranium, hollyhock, larkspur, ornamental cabbage and kale, pansy, poppies, snapdragon, and viola will all liven up the garden.

Winter Berries Count!

Another way to add a splash of brilliant color, and one that will make a particularly dramatic statement against a backdrop of pristine white snow, is to choose plants that give winter berries. These welcoming pops of color come in many more colors than the reds of hollies, viburnum, cotoneaster, checkerberry (aka boxberry and American wintergreen), skimmia, Japanese laurel, rowan, and rose hips, or the red and yellow combination of Firethorn.

There’s also beautyberry, which lives up to its glamorous name with pink-violet berry clusters; the spindle tree, which boasts orange-pink berries; and the aptly named Sorbus ‘Pink Pagoda.’ Juniper berries lend a stately blue to the winter landscape, while bayberry berries add a gentle silver tone. The luminous white berries of snowberry add a fairy-like touch to the garden, as do mistletoe berries, with the added benefit that hanging real mistletoe adds a tasteful flair to the home at Christmas. In addition to their delightful colors, berries can provide food for birds and other wildlife.

Hardscape ‘Flowers’

Painting a backyard bench peony pink, daisy yellow, or blueberry will not only add a burst of color to even the harshest winter, but will also help to protect it from the elements.

Paintbrush Power

Got a boring fence in need of a refresh? Add flowers in the form of a mural for year-round blooms. Not an artist? Paint the background a solid color and Google “large flower stencils.”

Planter Pizzaz

Opting for red, blue, teal, orange, yellow, or patterned plastic and fiberglass planters brightens a cold, dreary day, as do painted wood and metal planters. Be careful with glazed ceramic; it has to be high-fired and winter-rated for cold conditions.

Cheery Chairs

Few things inspire one to don a jacket and boots and go outside more than brightly colored Adirondack chairs. Whether the cheap plastic ones from a superstore or the much more expensive and durable resin plank chairs, they’re a great excuse to get a fire pit and enjoy the outdoors.
