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.[1][2] The flowers are cream-colored to yellow, with four sepals and four petals arranged in a cross shape, as is characteristic of the Brassicaceae.[3] It flowers from late winter to late spring.[4] 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.[5] It is fairly easily cultivated in gardens.[2]
Although not formally recognized as endangered, the Franciscan wallflower has a limited, discontinuous distribution. It is monitored at the Presidio of San Francisco, which was also its type locality.[3] The plant is propagated in a nursery there and then planted in its native habitat.[2]
