Clematis armandii 'Snowdrift' is a vigorous evergreen climber, perfect for screening unsightly walls or fences. In early spring, before the rest of the garden has woken up, it is covered in masses of scented white star-shaped flowers. It is prone to frost damage, so is best planted in a sheltered spot. Flowers March-April. Height 250-300cm. Supplied in a 3 litre pot.
