Not long ago, when English-style perennial gardens were all the rage, annuals fell from favor. But now they're making a comeback, as savvy gardeners rediscover the important role they play in beds, borders, and containers. As season extenders, annuals are unsurpassed.

When summer- and fall-blooming perennials die down, cool-season annuals kick into gear to fill gaps between established plants. There they'll grow and bloom through winter until their crescendo in spring.

They have other benefits as well. "Cool-season annuals are the easiest annuals to grow," explains horticultural consultant and garden designer Carole Kraft. "They're almost pest-free, but watch out for snails and slugs."

If you don't have room for lots of plants, you can still create dramatic effects. Even pocket gardens and containers pack a lot of flower power.

Design tips from a pro

Oakland landscape designer Bob Clark is a master at combining annuals with other garden plants for color.

Choose a color scheme. Clark prefers hot colors (orange, red, yellow) in winter because they're more warming and vivid. But in spring, he says, "people respond to pastels."

Take existing plants into account. If gray foliage plays a major role in your garden, stick to cool-colored flowers. If lime green and variegated yellow-and-green foliage are prominent, try hot colors. On the other hand, explains Clark, "deep green foliage is more forgiving. You can go with either cool or hot colors."

Buy plants with flowers in single colors, not mixes. Mixed colors often impart a garish or spotty look to garden beds, unless they've been specifically bred for compatibility (like Antique Shades pansies). Single colors, combined with your favorite similar or contrasting colors, have more impact.

Consider bloom time. When do you want your major show of blooms? For winter bloom (in mild climates), mix in plenty of calendula, pansies, primroses, or violas. Annuals like godetia, nemesia, and schizanthus bloom in spring. For a long season of bloom, combine plants that peak in both seasons.

Don't forget foliage. To create a foil for flowers, Clark uses annual leafy vegetables (cabbage, lettuce) and herbs (fennel, feverfew, parsley) with interesting textures and colors. Since most cool-season annuals (particularly winter-blooming types) are short, some of these plants ― especially fennel and mustard ― also provide height until later-blooming tall flowers emerge.

Consider the "visual pace." Gardens viewed up close allow for more complexity; plantings seen by passing motorists will be more effective when simple.

Hot fall color

The hot and spicy colors in this front yard in Piedmont, California, aren't for everyone; it takes courage to put on such a bold show.

In early spring, bright orange flowers contrast beautifully with foliage in deep purple, dark green, and lime green ― with tall red and yellow tulips as accents.

"It's a busy garden, but the masses of orange make it work," says the designer.

Snow white

Mild-climate gardeners needn't pine for snow in winter. It's easy to create the look of a light dusting of snow ― all frosty and cool ― with an all-white planting. Designed for a long season of bloom, the planting shown at left covers a two-tiered rock retaining wall.

Primrose and cyclamen tucked among the stones bloom from fall through spring. Bacopa, a perennial accent, provides the lacy white flowers around them (it freezes back below 28° to 30°).

Come late winter, white narcissus pop up through the garden, and by spring the garden is in its full glory. White-flowered Chrysanthemum paludosum and Loropetalum chinense fill the center pot.

A touch of sunshine

Although Carole Kraft specializes in perennials, she finds that annuals are her mainstay in winter; they provide abundant color when perennials are dormant.

The mixed pocket garden she designed to liven up the front entry pictured at left ― filled with cool, soft purples and lemon yellows ― is nearly everblooming. "The owners wanted something bright and cheerful but not overwhelming, says Kraft. "Lavender and purple cool down the bright yellow, so the garden is more peaceful."
