Erysimum Torulosum

Cluster of bright yellow, scented flowers open on thin stems bearing narrow leaves and later twisted seed pods. A rare species in the wild, it is occasionally encountered on rocky ridges, where it is known as the 'sand-dwelling wallflower'. It likes gritty, well drained soil and flowers from mid spring to early summer. Native to British Columbia, Washington and Oregon, it is found at high elevations from 900 to 2200 m in the Cascade and Olympic Mountains as well as on Vancouver Island.
