Lasurstern Clematis

Lasurstern Clematis is a truly exotic looker, covered in enormous flowers up to 25cm in diameter from May to June, with a second flush in September. The blooms are an exquisite shade of clear lavender blue, with deep pleated midribs and crimped edges.

After the show of flowers, the large lime-yellow anthers remain to produce an attractive display of seedheads through the autumn and into winter.
