When you think of perennials, yucca probably isn't the first plant that comes to mind. But besides its handsome, spiky foliage, yucca is also prized for its tall, fragrant clumps of creamy white bell-shaped blooms. Its nectar-rich flowers will also lure colorful hummingbirds to your yard. In this country garden, yuccas bloom alongside a patch of bright red Asiatic lily.

As versatile as they are colorful, flowering shrubs should play a starring role in your perennial border. Some of the best low-growing bloomers include azalea, viburnum, spirea, hydrangea, and potentilla. Plus, some shrubs like this Spirea bumalda 'Goldflame' produce both colorful flowers and foliage. This easy-care mounding plant blends beautifully with the blue flower spikes of 'May Night' perennial salvia.

When you design your garden, remember green is also a color; mix different shades together to make a memorable garden without relying on a circus of bright flowers. In this shady corner, tall cinnamon ferns tower over a subtle bed of white-flower tiarella, giving the space a sophisticated yet restful look. Cinnamon fern gets its name from the cinnamon-color fibers found near the frond bases.

Grow Tropical Plants for Bold Color

Red Hibiscus and small blue flowers
Paul Vandevelder

You don't have to live in the tropics to enjoy hibiscus's big, bold blooms. These warm-weather beauties have a variety of cold-hardy relatives that prefer growing in the north. Hardy hibiscus is easy to care for, often growing 6 feet tall in one season and producing dinner-plate-sized flowers in the late summer and fall. Each winter, they'll die back to the ground but pop back up when the temperatures soar in the early summer. In this garden, this red-flowered hibiscus makes a stunning pair with delphinium elatum.

Buy It: Multi-Colored Delphinium Mixture ($12, The Home Depot)

Include Multicolor Flowers for a Two-Tone Show

Purple irises in field

Most perennials come in solid colors, but some offer varieties with bicolor blooms. Bearded iris, peony, coreopsis, gaillardia, and phlox are just some examples of perennials with bicolor options. And, by selecting bicolor varieties, you'll double the color in your beds and borders. In this spring border, it just takes purple allium and bicolor bearded iris to create a tapestry of bloom.

Flowering Vine Plants Can Brighten Fences and Arbors

Bob Stefko

The crowning glory of any landscape, flowering vines will quickly smother a fence or arbor in color. But left unchecked, some vines, such as trumpet vine or wisteria, may smother perennials growing nearby. On the other hand, Clematis only grows 5-10 feet tall, making it an ideal plant combination with perennial flowers. This sun-loving vine also comes in a wide variety of flower shapes and colors, so you have plenty of options for any garden style. In this border, 'Jackmanii' clematis and 'Harvest Moon' coneflower are a feast for the eyes.

Consider Year-Round Appeal

Dwarf junipers, arborvitae, and daylilies
Kindra Clineff

Sadly, most perennials die back to the ground after the first hard freeze. This means that your border in cold climates will look bare for several months of the year. Team some low-growing evergreens with your perennial flowers instead of having nothing to look at during long winter days. During the spring and summer, the evergreens will provide consistent color, and in the winter, they'll keep the color show going. In this border, various dwarf junipers and arborvitae stand guard over clumps of daylilies and other flowers.

Include Tender Perennials

Cannas with serpentine perennial border
Rob Cardillo

Large-leaved cannas make a dramatic statement in any garden. These heat-loving plants are perennial in frost-free regions, but they must be dug and stored over the winter in the north (because they're not cold hardy, they're called tender perennials). Available in standard types that can grow 6-8 feet tall and dwarfs that stay below 4 feet tall, cannas are easy to squeeze into the flower border. In this garden, a mass of red- and green-leaf cannas form a wall of color at the end of a long, winding perennial border.

Plant Perennials in Large Groups

Oriental lilies and eryngium
Kindra Clineff

Building a gorgeous garden isn't like building an ark. You don't need two of everything to make a big impact. Instead, group your favorite perennials in large drifts or clumps that take your breath away when they all bloom at the same time. This border, for example, stands out because it contains a solid ribbon of more than 20 Oriental lilies behind a large clump of blue-gray eryngium.

Grow a Living Bouquet

Yellow Gaillardia, black and blue sage, and Shasta daisy
Jamie Hadley

If you aren't sure what perennial plant combinations work best, think about what flowers would make a beautiful bouquet. If perennials look good in a vase, they'll certainly look good in your garden. In this mixed border, perennial salvia, yellow gaillardia, and Shasta daisy work together as a living flower arrangement.
