Centranthus ruber 'Albus'
valerian (syn Valeriana Albus)
This free-flowering perennial has slightly fleshy blue-green leaves on upright stems, topped with sweetly scented, off white flowers with a pinkish tinge from late spring. Cut back after flowering to encourage a second flush.
How to care for Centranthus ruber Albus:
Centranthus thrives in well-drained soil and full sun, making it perfect for gravel gardens, coastal planting, and dry borders. It tolerates poor, sandy, or chalky soils and will even grow in walls or cracks in paving.
Once established, it is drought-tolerant and requires little watering, though occasional deep watering in prolonged dry spells will encourage better flowering.
Deadhead regularly throughout the summer to prolong flowering. In autumn, cut the plant back down to the ground and compost the dead stems.
Self-seeding freely, it may need occasional thinning to prevent overcrowding, but this also allows it to naturalise beautifully in the right setting.
