Clematis 'Avalanche' is a spectacular evergreen climber prized for its deeply lobed, parsley-like dark green foliage that provides lush year-round visual interest. During the early spring months, this clematis bursts into an extraordinary profusion of pure white, star-shaped flowers that elegantly blanket the entire plant. Because it lacks the twining tendrils of many traditional varieties, this climber requires gentle tying to a supportive structure or can be left to cascade beautifully over retaining walls. While remarkably vigorous in milder climates, this evergreen vine prefers a sheltered, sunny position with cool, well-draining soil and may require some protection from severe winter frosts. Thanks to its naturally trailing and moderately compact growth habit, this clematis performs exceptionally well in large patio containers where its cascading floral display can be closely admired.
