Weigela, flowers, trees

A fast-growing shrub that's available in a range of colors, weigela (Weigela florida) offers a showy quality of blooms. "Bare stems give rise to 3 inch long by 1 inch wide leaves in spring followed by a burst of color from the flowers," says Adrienne Roethling. "Numerous, tubular shaped flowers are born at every leaf."

Typically the flowers are pink or white, but newer varieties come in red, magenta, or white and change to pink. This plant should reach maturity in about three years, growing up to 12 inches tall in 12 months.

Viburnum flowers trees

A low-maintenance shrub with fragrant white flowers, viburnum blooms from spring to fall. Coppertop Sweet Viburnum (Viburnum odoratissimum 'BRANT01') is a fast-growing variety that's commonly grown as a privacy hedge, but can also be grown as an accent shrub. "This has quickly become one of my favorite screening plants," says Jim Putnam from Southern Living Plant Collection. "It's a very fast-growing evergreen shrub and all of the new growth is a beautiful coppery color that matures to a striking dark green. Mine have tripled in size in one year since I planted them."

Panicled Hydrangea, Flowers

Hydrangeas are widely recognized for their beautiful, showy blooms, but they're also a great plant to grow if you're looking for something that grows fast. "Panicled hydrangea (Hydrangea paniculata) is a deciduous shrub that produces medium to large, elliptical to oval shaped, bright green leaves in mid-spring," says Adrienne Roethling, garden director for Paul J. Ciener Botanical Garden.

Shortly after, panicles of flowers appear in a cone-shaped inflorescence. "Flowers last well throughout the summer months and turn a red or cinnamon color in fall," says Adrienne Roethling. Expect the shrub to reach maturity within three years, growing 12 inches or more a year if conditions are ideal.

Heucherella flowers

Play up the sense of drama in the shaded areas of your yard with Twilight' Heucherella (Heucherella hybrid 'Twilight' PP25723), which has dark foliage in shades of purple, burgundy, and silver tones. It's also a great shrub to plant if you're looking for something to complement the colors of surrounding plants. “The top of each leaf is a charcoal green that is accented by a bright purple underside," says Putnam. "With that pop of contrast, it’s an absolutely stunning plant.”

Bottlebrush Buckeye, Flowers

Although bottlebrush buckeye (Aesculus parviflora) produce more flowers in locations with greater sunlight, the shrub can still grow and thrive in shade. "Tubular white flowers arranged in breathtaking candlestick-like panicles make bottlebrush buckeye a great summer-flowering shrub for shady areas." The panicles, which can grow up to 1 foot in length, attracts butterflies and hummingbirds.

Maple-Leaved Viburnum, White Flowers

Maple-leaved viburnum (Viburnum acerifolium) is more shade tolerant than most other viburnums, making it a great addition to the dimly lit patches of your yard. "Small, white lace-cap flowers in spring give way to berries loved by birds that grace the maple-like leaves of Maple-leaved Viburnum," says Young "Its bright green foliage becomes a distinctive bright red, pink, or purple in the fall."

Mahonia flowers

Mahonia is an evergreen shrub with intricate leaf texture that infuses movement into shady spaces. For a thorn-free variety, try 'Soft Caress' Mahonia (Mahonia eurybracteata 'Soft Caress' PP20183). It has deep green foliage that shines year-round and bright yellow flowers that provide a pop of color in early winter. “This variety of Mahonia has a beautifully compact growing habit with foliage that mimics bamboo, without the aggressive spreading habit," says Janet Sluis of Sunset Plant Collection.

Rattlesnake Master, White Flowers

Balls of tiny flowers sit atop the tall spikes of the perennial rattlesnake master, a drought-tolerant plant with pale green summer blooms. Though it looks like a thistle, this plant is a member of the carrot family—crush the leaves to catch the familiar scent.

Mountain Mint, Flowers

Another member of the mint family that draws pollinators is mountain mint, a low-maintenance herbaceous perennial  with pink-speckled blooms that open in midsummer. "The crushed foliage has a minty aroma, different from the mint types grown as common herbs, but still minty overall," says Talabac. "It's popular with a lot of other pollinators, like native bees, solitary wasps, and honeybees, teeming with activity when a clump is in peak bloom."

Summersweet flowers

Summersweet, a deciduous shrub, gives off a sweet scent from its off-white or light pink blooms in the later part of the summer, drawing pollinators after other plants have stopped flowering. "It's later to leaf-out in spring than most flowering shrubs, so don't be alarmed if branches are still bare when other garden plants start regrowing," says Talabac.
