Similar Species:

The notched petals of the white flowers bear a resemblance to those of species of the genus Draba. However Hoary Alyssum is a taller plant with leaves on the stem and an early spring flowering period. The round, ovate seed pods will distinguish this species from species of Capsella, Lepidium, and Thlaspi with flattened seed pods.
