- Description
-
Red valerian is a weedy wildflower in the Medeterainian parts of Europe, growing on chalky cliffs and stone walls. It can take the form of a plant or shrub depending on conditions. In the US, plants growing in gardens have the tendency to naturalize. After blooming, seed heads will replace the blooms. These seed heads are similar in appearance to a dandelion and are dispersed by the wind. Deadheading is necessary to prevent the spread of this invasive specimen. The large flower clusters are showy and in shades of red to purple. In cool summer areas, the plant will repeat bloom throughout the summer into fall.
In the US it can be found growing in the wild in states located along the western coast, midwest as well as Hawaii. It does not grow well in hot humid climates. This plant is listed as invasive in some counties and has high invasive potential. Please choose a native alternative.
Its leaves and roots are both edible. The leaves can be eaten raw or lightly boiled. The roots can be used in preparing soups.
Larvae of some Lepidoptera butterfly and moth use this plant as a food source.
Insects, Diseases, and Other Plant Problems: No serious issues. Weedy. Has invasive tendencies. Aphids and mealy bugs may be bothersome. Continuously wet soil can lead to crown rot.
