Plant Profile: Valeriana rubra

Valeriana rubra, also known as Centranthus rubra, is a wildflower commonly found in Europe, thriving on chalky cliffs and stone walls. In the United States, it often naturalizes in garden settings. After the flowering period, the plant produces seed heads that resemble those of a dandelion, which are carried away by the wind. To control its spread, it is important to deadhead the flowers regularly, as this species can become invasive.

In the U.S., Valeriana rubra can be spotted in the wild along the western coast and in Hawaii.

Both the leaves and roots of this plant are edible; the leaves can be consumed raw or lightly cooked, while the roots are suitable for use in soups.

Additionally, the larvae of certain Lepidoptera species, including butterflies and moths, rely on this plant as a food source.

Regarding pests and diseases, Valeriana rubra does not face significant threats, but it can become invasive. Aphids and mealybugs may pose some challenges, and overly moist soil conditions can result in crown rot.
