CLEMATIS VITICELLA A robust species clematis with poise and elegance. It does not have the temperament, or perhaps vulgarity, of an over-bred hybrid. From mid-summer onwards the delicate blue flowers dance on short stalks, even in the slightest breeze. The blooms are shaped like Victorian lampshades with the inside being slightly darker than the outside giving a magical effect. It is easy to prune. -Cut it hard to the ground in February, mulch with a hearty dose of manure. and leave it alone. It is ideal to clothe a pergola or to disguise the drabness of a once-flowering rose.
