General Culture:
Easily grown in average, dry to medium wet, well-drained soils in full sun to light shade. This flower is a biennial, so self-seeding will be necessary for it to remain in the garden. Cut back spent flowering stems only after seed has been harvested or has ripened and fallen to the ground.
Noteworthy Characteristics:
Western wallflower is broadly distributed throughout western North America. It is also native to Missouri where it primarily occurs on rocky open ground, limestone glades and bluffs in the central part of the State (Steyermark). It is an erect biennial that features a dense, rounded flower cluster (raceme) of showy, 4-petaled orange to yellow-orange to maroon to nearly white flowers (3/4" wide) atop a leafy upright stem growing 1-2 tall. Linear to narrow oblong leaves (to 3" long) appear in a basal rosette and along the stem. Flowers give way to 4-angled seed pods (to 4" long). Capitatum (meaning head in Latin) is in reference to either the head-like shape of the flower cluster or the knobby stigma.
Problems:
No serious insect or disease problems.
Uses:
Rock gardens. Native plant gardens or naturalized areas.
