Armandii Snowdrift Clematis

The Only Evergreen Clematis — With Fragrant White Blooms in Early Spring

Armandii Snowdrift Clematis (Clematis armandii 'Snowdrift') occupies a unique position among flowering vines: it is one of the very few truly evergreen clematis varieties, maintaining its bold, glossy, dark-green foliage year-round while most other clematis go completely dormant in winter. In early spring — often as early as February or March — it erupts in a profusion of pure white, vanilla-scented flowers that cascade along every stem, creating one of the most spectacular early-season floral displays of any vine. It is a vigorous, fast-growing climber that quickly covers trellises, fences, pergolas, and walls with dense, attractive foliage, providing privacy and structure throughout the year.

Why Armandii Snowdrift Stands Apart

• Evergreen foliage year-round — one of the very few evergreen clematis varieties; bold, glossy, dark-green leaves provide year-round coverage, privacy, and structure
• Earliest-blooming clematis — flowers in late winter to early spring (February–March in most zones); one of the first flowering vines to bloom each year
• Fragrant white flowers — pure white blooms with a sweet vanilla fragrance; flowers cover the entire vine in a spectacular early-spring display
• Fast, vigorous growth — can grow 20–30 ft; quickly covers large structures with dense, attractive foliage
• Excellent privacy screening — dense evergreen foliage provides year-round privacy on fences, walls, and pergolas
• Pollinator-friendly — early blooms provide critical nectar for bees and butterflies emerging from winter

Hardiness & Growing Zones

• USDA Hardiness Zones: 7–9
• Zone 7: Hardy in-ground in most zone 7 locations; plant in a sheltered location with protection from harsh north and west winds; foliage may bronze or partially drop in severe winters but regrows in spring; flower buds may be damaged by hard freezes below 10–15°F
• Zones 8–9: Ideal conditions; fully evergreen with vigorous growth and prolific early-spring blooming
• Sunlight: Full sun to partial shade (full sun produces the most prolific blooming; roots prefer to be shaded — mulch around the base or plant a low groundcover at the base)
• Soil: Moist, well-drained, slightly alkaline to neutral (pH 6.5–7.5); clematis prefer “cool feet, warm head” — shade the root zone while the top growth reaches for sun
• Mature size: 20–30 ft long; vigorous grower that requires a sturdy support structure
• Bloom time: Late winter to early spring (February–March in most zones)

Pruning Notes

Clematis armandii is a Group 1 (early-blooming) clematis — it blooms on old wood set the previous season. This means pruning timing is critical: prune only immediately after blooming (March–April), removing dead or damaged wood and cutting back stems that have outgrown their space. Never prune in fall or late winter, as this removes the wood that carries next season’s flower buds. Light annual pruning after bloom keeps the plant tidy and encourages vigorous new growth for the following year’s flowers.

Planting & Care Tips

Plant near a sturdy support structure — a mature Armandii is heavy and requires a strong trellis, fence, or pergola. Shade the root zone with mulch or a low groundcover while allowing the top growth to reach full sun. Water consistently during the first growing season; once established, it is moderately drought-tolerant. Fertilize in early spring with a balanced slow-release fertilizer. Avoid disturbing the roots once established — clematis dislike being transplanted.
