Botanical Identity

Centranthus ruber, commonly known as red valerian or Jupiter’s beard, is a perennial flowering plant in the Caprifoliaceae family. Despite its common name, it is not a true valerian but shares a similar appearance. Native to the Mediterranean region, including southern Europe and parts of North Africa, it has become naturalized across much of Europe and even in parts of North America. It is valued for its ability to thrive in dry, rocky soils where few other plants grow.

Plant Description

Centranthus ruber typically grows 60 to 90 centimeters tall, forming bushy clumps. It has grey-green, lance-shaped leaves that are arranged oppositely on fleshy, branching stems. The plant is very drought-tolerant and thrives in full sun and well-drained soils, often seen in old walls, rocky outcrops, and disturbed urban areas. Its hardy nature and long flowering period make it a popular choice for dry gardens and wildflower plantings.

Flowers and Fruit Characteristics

The plant produces dense clusters of small, tubular flowers, usually in shades of deep pink, red, or occasionally white. Blooming from late spring to early autumn, the flowers are highly attractive to bees, butterflies, and other pollinators. Each floret has a long spur, and the flower heads are rounded or dome-shaped. After flowering, Centranthus ruber forms small, feathery seed heads that are easily dispersed by wind.
