Clematis × cartmanii 'Joe'

winter flowering clematis (group 1)

Product Image
A profusion of small, waxy, pure white flowers on purple-tinted stems appear in April amid finely cut, deep green leaves. This dwarf, evergreen clematis requires a sunny site and protection against frosts. In all but the warmest areas of the country it's best grown in a conservatory or cool greenhouse in a large patio pot.

How to care for Clematis × cartmanii Joe:

No routine pruning is necessary. If the spread of the plant needs to be restricted prune immediately after flowering, cutting back overlong shoots to healthy buds. Apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the base of the plant in early spring.
