Centranthus ruber 'Albus'
These cool-white fluffy flowers, which don’t brown when they fade, blend well with soft silvers but add some dusky Purple-leaved sage (Salvia officinalis ‘Purpurascens) for woolly contrast
- Position: full sun
- Soil: well-drained, neutral to alkaline
- Rate of growth: fast-growing
- Flowering period: May to October
- Hardiness: fully hardy
Airy clusters of white flowers appear from July to October on tall, fleshy stems with glaucous leaves. This white form of red valerian is long flowering and easy-to-grow and combines well with many different plants. It's ideal for a sunny wildflower or seaside garden with poor, but well-drained soil, or for growing between the cracks in walls. It self-seeds freely and prefers a chalky or alkaline soil.
- Garden care: Deadhead regularly throughout the summer to prolong flowering. In autumn cut the plant back down to the ground and compost the dead stems.
