Clematis × cartmanii 'Joe'
clematis (group 1)
- available to order from summer
- 2 lt pot (60cm cane)
- Position: full sun
- Soil: fertile, well-drained, neutral soil
- Rate of growth: average
- Flowering period: April
- Hardiness: frost hardy (will need winter protection)
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.
- Garden care: 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.
