Centranthus ruber 'Albus'

Easily grown in average to sandy, medium moisture, well-drained soils in full sun to part shade. Prefers slightly alkaline soils in full sun. Limestone may be added to acidic soils. Tolerates dry soils. Does well in poor, infertile soils where it usually grows in a more compact form. Freely self-seeds in optimum growing conditions to the point of being somewhat invasive and weedy. Promptly remove (shear if large planting) spent flower stems to encourage additional bloom and to prevent seeds from forming. Plants are generally less vigorous in the hot and humid summers of the Southeastern U.S. than in cool summer climates.

Common Name: red valerian
