With us in St John's Newfoundland it doesn't flower until June; just as the leaves come out on the trees! Very hardy though, as you would expect from a plant that grows in Siberia.

A deciduous climber/rambler from Europe.

Has 3-5, mid-green, lance shaped, toothed leaflets. Bears nodding, bell shaped, blue flowers with white centres borne on the previous years shoots. Fluffy seedheads after flowering.

Flowers March-May but can have another flowering later in the year on new growth.

Likes a well drained, fertile soil in sun or partial shade, it will tolerate cold areas of a garden. Roots like to be in a cool shady spot.

Prune after main flowering, removing the dead flowers and stems and general tidying up.

It is one of the hardiest Clematis and is very compact, suitable for small gardens and large containers.
