Erysimum franciscanum
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 Counties. It is a member of the genus Erysimum in the mustard family, the Brassicaceae.
The plant is a biennial or short-lived perennial. The flowers are cream-colored to yellow, with four sepals and four petals arranged in a cross shape, as is characteristic of the Brassicaceae. It flowers from late winter to late spring. The plant prefers open scrubby areas with a fair amount of sunlight, but can flourish on a range of soils including disintegrating serpentine, gravelly and sandy soils. It is fairly easily cultivated in gardens.
