Excellent relatively small growing climber with nodding, bell-shaped, lemon yellow flowers, followed by silky seed heads.

All clematis prefer alkaline soil but will normally tolerate other soil types. Requires regular supply of moisture. When planting, make the hole deeper than usual, as a precaution against Clematis wilt.
Prune hard back in late winter.

From seed, sown in late winter or spring. Can flower the same year.

Good for small gardens and growing through shrubs.
