About San Francisco Wallflower (Erysimum franciscanum) 5 Nurseries Carry This Plant Erysimum franciscanum, commonly known as the Franciscan Wallflower or San Francisco Wallflower, is a plant endemic to the northern California coast, from Sonoma to Santa Cruz County. It is a member of the wallflower genus in the mustard family, the Brassicaceae. The plant is a biennial or short-lived perennial. The flowers are cream-colored, with four sepals and four petals arranged in a cross shape, as is characteristic of the Brassicaceae.
