Erysimum capitatum (Coastal Wallflower)

Erysimum capitatum (Coastal Wallflower) is an erect biennial or short-lived perennial boasting densely crowded clusters of orange, yellow, or reddish flowers atop leafy upright stems from late spring to mid-summer. Providing weeks of color, the four-petalled flowers are attractive to bees, butterflies, and other pollinators. The blossoms give way to 4-angled seed pods. Although short-lived, Coastal Wallflower has a strong tendency to self-seed and keeps a presence in the garden. The foliage of narrow oblong leaves, 3 in. long (7 cm) appears in a basal rosette and along the stems. Showy in a wildflower garden, Coastal Wallflower looks great when planted in swathes or drifts, or interspersed with other water-wise plants.
