Erysimum capitatum

Western Wallflower is a very widespread biennial or short lived perennial. It occurs from Alaska to nearly Mexico and throughout the west coast. The first season is spent as a rosette of thin undulating leaves. In the second year it extends, forms branches and achieves multiple flower spikes. The species is best described as yellow/orange with some slight variation in these seed grown plants. In Oregon its is widespread but it has all but disappeared from some biomes, the Willamette Valley for instance, a victim of non native invasives. To 22″ tall in bloom. You  may get a third season but it is much less of a show.Best to let this plant set seed and die ensuring a new generation of plants. Leave open disturbed sites for re-sowing.  A gravel mulch will encourage this as well and it appreciates average to enriched soil and light consistent water to establish. The following year it can rely on only what fall from the  sky. Blooms appear for several weeks in late spring. Loved by pollinators with a special draw to butterflies. Common associates in the wild are Dodecatheon hendersonii,  Mitella , Ranunculus occidentalis, Nemophila. Oregon native plant
