Clematis ‘Boulevard® Olympia™’ – A Compact Climber Bursting with Purple Elegance
Clematis ‘Boulevard® Olympia™’ (also registered as Clematis ‘Evipo099’ PPAF) is a standout variety in the celebrated Boulevard® series. Bred by renowned clematis expert Raymond Evison. It has a compact size and prolific bloom. This deciduous, perennial climber adds vertical charm and vibrant color to small spaces, containers, and garden beds.
A member of the Ranunculaceae family (the Buttercup family), Clematis ‘Boulevard® Olympia™’ exemplifies the series’ strengths: repeat flowering, ease of care, and floral abundance. It grows 3 to 5 feet (90 to 150 cm) tall and spreads 18 to 24 inches (45 to 60 cm), making it a perfect choice for patio gardens, balconies, and smaller trellised areas.
Unique Flowering Habit of Clematis ‘Boulevard® Olympia’
Unlike many Clematis, Olympia™ produces its large, violet-blue flowers not only from stem tips but also from the leaf axils. This unusual trait ensures an exceptional floral display that covers much of the vine. Each bloom measures 4 to 5 inches (10 to 12 cm) in diameter and displays striking purple petals streaked with magenta and accented by a center of buttery-yellow, fringed anthers. This unique combination attracts pollinators like bees and hummingbirds throughout its long blooming season.
Blooming Season and Reblooming Ability
This clematis begins flowering in late spring and continues through early summer, followed by a second flush in late summer into fall. Regular deadheading after the first bloom can enhance reblooming. With its showy, long-lasting blossoms, ‘Boulevard® Olympia’ brings a reliable succession of color to garden spaces from May into early autumn.
Growing Conditions for Clematis ‘Boulevard® Olympia’
Light
Clematis ‘Olympia’ thrives in full sun (at least 6 hours per day) or partial sun (4-6 hours), with a preference for morning sun and some afternoon shade, particularly in hotter climates.
Soil
This variety requires well-draining, fertile soil enriched with organic matter. A slightly acidic to neutral pH (6.0 to 7.0) is ideal. Avoid heavy clay unless amended to improve drainage.
Watering
Water deeply when the top inch of soil feels dry. Consistent moisture is essential, especially during establishment. Apply mulch to maintain cool roots and retain soil moisture.
Fertilizing
Feed with a low-nitrogen fertilizer (5-10-10) in early spring and again after the first flowering flush. Alternatively, use a slow-release balanced fertilizer (such as 18-5-10) to support steady growth through the season.
Growth Habit and Uses in the Garden
Compact and moderate in growth rate, Olympia™ is ideal for container gardening, vertical structures like trellises or obelisks, and mixed perennial beds. It can be trained for vertical displays or allowed to sprawl as a groundcover. It pairs well with shrubs, roses, and other clematis varieties in layered planting schemes.
Gardeners value this clematis for its tidy growth habit, deer and rabbit resistance, and tolerance to urban conditions and black walnut trees.
Pruning Clematis ‘Boulevard® Olympia™’
Belonging to Pruning Group 2, Olympia™ blooms on both new and old wood. In late winter or early spring, cut back stems to about 6 inches (15 cm) above the ground to encourage vigorous new growth. After the first flowering flush, lightly trim some stems back to a strong side shoot below the bloom to promote the second wave of flowers.
Pests, Diseases, and Maintenance
This clematis variety is generally low-maintenance and pest-resistant, though it may attract aphids or slugs in certain conditions. Watch for signs of clematis wilt or powdery mildew, especially in humid climates. Ensure good air circulation and avoid overhead watering to reduce disease risks.
Winter and Container Care
Hardy in USDA Zones 4 through 9, Clematis ‘Boulevard® Olympia™’ tolerates cold climates well when planted in the ground and mulched in winter. In containers, protect the roots by sinking pots into the ground or using insulating mulch. Prune and reduce watering during winter dormancy.
Final Thoughts on Clematis ‘Boulevard® Olympia™’
Clematis ‘Boulevard® Olympia™’ delivers exceptional garden performance in a small package. With its striking purple blooms, ease of cultivation, and ability to flower from top to bottom, it embodies the best of Raymond Evison’s breeding work.
