Also known as rose rock cress, this evergreen herbaceous perennial is a member of the mustard family, Brassicaceae, that also includes alyssum, cabbage, and broccoli.  It is endemic to California and grows mostly on rocky scrub  in the San Francisco Bay Area and at low elevations in the nearby California Coast Ranges but is also grown as a garden plant.  The plants produce flat rosettes of hairy dark green  leaves two to three inches long and slender unbranched hairy stems  six to twelve inches tall that carry short heavy racemes of fragrant purplish pink flowers.  The four petaled  flowers are cruciform and appear in the spring. Coast rock cress is drought and heat tolerant but cannot do well where high temperatures are accompanied by high humidity.
