Discussion

Malephora crocea is grown as an ornamental and often sold as a ground cover for landscaping. It is cultivated along freeways as far north and inland as Fresno, California.

Two varieties of Malephora crocea have been recognized: var. crocea, with the adaxial surfaces of the petals orange and the abaxial surfaces purplish; and var. purpureocrocea (Haworth) H. Jacobsen & Schwantes, with petals purplish on both surfaces, which is grown for ornamental purposes and is not naturalized in the flora.
