Information about the top 10 varieties at your stores:
Emerald Colonnade® Holly
This handsome and versatile male evergreen holly with a natural pyramidal form creates a superb hedge, screen, or windbreak. Dense, glossy, bright green foliage is tolerant of shearing, making it an excellent topiary specimen or formal accent to entryways or gardens. Small cream-colored flowers do not produce berries.
Orange Twist Brush Cherry
Glossy orange foliage on upright, twisting branches creates a unique and colorful year-round display. White, pincushion-like blooms appear in spring, followed by purplish berries. The leaves transform to green with age, as new growth continues to emerge. Great hedging and screening shrub. Use in containers as an artful specimen or clipped topiary.
Summerlasting™ Raspberry Crape Myrtle
Why wait for colorful crape myrtle blooms' Bright pink flowers appear weeks earlier than other dark foliage varieties, and rebloom without the need for deadheading, filling your summer with color that pops in front of black foliage. This compact, dwarf variety is perfect for smaller landscapes, or plant en masse for a dramatic statement.
Rock & Roll® Peruvian Lily
An award-winning combination of dynamic foliage and vivid scarlet-orange flowers, prized for cut flower arrangements. A compact habit with brightly variegated leaves - creamy white with green margins - set the stage for continuous blooms from spring to fall. A thrilling choice for landscape or container. An herbaceous perennial.
Bridal Veil® Agapanthus
Clusters of big pure-white flowers are held on shorter stems above wide, strap-like leaves. Both foliage and blooms are densely held, making for a wonderfully compact plant. The smaller size is great for containers or for massing in the front of perennial beds. Evergreen; may go dormant in cooler areas.
Burgundy Queen® Bougainvillea
This showy climber provides a double shot of color with every new flush of growth emerging a dramatic dark burgundy, followed by deep burgundy flower-like bracts. Use for a lush tropical effect on arbors, trellises, and spilling over fences. Evergreen in frost-free regions; can be used in colder climates as a summer annual for patio containers and hanging baskets.
Flame Thrower® Redbud
Light-pink spring flowers are followed by an ever-changing display of colorful foliage that continues all the way to fall. New foliage emerges burgundy, fades to yellow, and matures to green. Branches display all the colors at once for a stunning effect. A wonderful landscape specimen. Deciduous.
Brakelights® Red Yucca
Vibrant, brake light-red blooms are a great color improvement to this species! This compact newer selection rarely sets seedpods, meaning more prolific flowering over an exceptionally long season. Use in mass plantings for a dramatic effect in xeriscape and waterwise gardens. Good container specimen. Evergreen.
