Erysimum asperum

Western Wallflower, Siberian Wallflower, Blister Cress

Grown for their showy, orange or yellow, usually fragrant flowers, these annuals and perennials are very drought-tolerant and live longer when grown in lean, rocky soils. Many are naturally found on rock walls or barren slopes. They require sun and well-drained soils. Start by seed or cuttings. Remove old flower stalks to encourage new blossoms.
