Valerian (Centranthus Ruber mix) 40 seeds (#1695)

Centranthus ruber, commonly called red valerian or Jupiter’s beard, is a well-branched, bushy, clump-forming, woody-based perennial which is valued for its ability to produce, often in poor soils, a showy bloom of star-shaped crimson, pink or white flowers from spring to frost.
Although native to the Mediterranean, this plant has escaped gardens and naturalized in certain parts of the United States, particularly along the west coast.
Flowers appear in dense terminal clusters (cymes) atop upright to relaxed stems rising above the foliage to 40-80cm tall. Flowers are fragrant. If not deadheaded, flowers give way to dandelion-like seed heads which are typically disbursed around the landscape by wind. Fleshy, sessile, oval to lanceolate leaves (to 10 cm long) are gray-green.
Ideal fro cottage gardens, naturalized areas, stone walls, slope or bank cover to help combat erosion, borders, particularly as specimens or in small groups where planting can be more easily managed. Effective ground cover.
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.
