Train up narrow railings and posts on stoop or porch. Unique, deeply dissected foliage and golden stamens are best appreciated up close near terrace and patio.
Flower Color White
Foliage Color Green
Companion Plants Maiden Grass (Miscanthus); Hydrangea (Hydrangea); Daylily (Hemerocallis); Japanese Maple (Acer); Butterfly Bush (Buddleja)
Care Instructions Thrives in enriched, well-drained soil, with roots sheltered and top growth in the sun. Mulch soil surface to conserve moisture. Water deeply, regularly in first growing season to establish root system; reduce frequency once established. Apply fertilizer when new growth begins in spring. Provide trellis or arbor support. Pruning Group: 1
History A seedling selected in 1992 from a cross-made at Blackthorn Nursery, England by renowned plantsman Robin White. A hybrid between Clematis paniculata and Clematis marmoraria-both evergreen species native to New Zealand. An Avalanche of pure white flowers cascade from previous season's wood in spring providing a superb contrast with the pinked edge dark leathery green foliage. This beautiful vine is equally content climbing on a wall or rambling along the garden floor.
Lore In its homeland of New Zealand, this plants ancestor, C. marmoraria is an evergreen rock hugging crevice plant with little resemblance to the resulting cultivar.
