Clematis heracleifolia 'Cassandra'
herbaceous clematis (Group 3)
- Position: full sun or partial shade
- Soil: fertile, well-drained, neutral soil
- Rate of growth: average
- Flowering period: July to September
- Other features: deeply lobed light green leaves
- Hardiness: fully hardy
Hyacinth-like, lavender-blue, late-summer flowers appear at the tips of the leafy stems. This herbaceous clematis does not climb, but forms an open bush and is ideal for growing through a sunny mixed border where it can scramble amongst its neighbours.
- Garden care: Cut back the stems to the base of the plant each winter and apply a mulch of well-rotted garden compost around the plant, avoiding the immediate crown. Use twiggy prunings, ring stakes or bamboo canes to provide support.
