Quick facts

About Red valerian

Centranthus ruber, commonly known as Red Valerian, is a vigorous and low-maintenance perennial plant, valued for its dense clusters of deep pink to crimson-red flowers. Its abundant and prolonged blooms, from late spring well into autumn, make it ideal for garden borders, rockeries, or naturalizing sunny, dry areas, attracting butterflies and bees. Its wild yet ornamental appearance makes it an excellent choice for Mediterranean-style or low-water gardens.

Native range

Mediterranean region of Europe and North Africa

Care tips

Red Valerian thrives in full sun, requiring at least 6 hours of direct light daily for optimal flowering. It is extremely drought-tolerant once established, so watering should be sparse, especially in humid climates, avoiding waterlogging. It prefers well-drained soils, even poor or calcareous ones, and a common mistake is overwatering, which can lead to root rot and less compact growth. Deadheading spent flowers will encourage continuous blooming.
