Erysimum 'Erysistible Tricolor'

Erysimum 'Tricolor' is a compact, upright, bushy, often short-lived, evergreen perennial with linear to lance-shaped, sparsely-toothed, dark green leaves. From spring to late summer, dense racemes of fragrant, bright flowers inpastel  shades of purple, yellow and pink appear, making it a bright and cheery addition to any border, pot or rock garden.  Very hardy, even surviving harsh winters, but best treated as a biennial, although it can survive longer.  Prefers moist but well drained soil in sun or light shade.
