(Helianthemum) Also known as Rock Rose, this low growing perennial sports tons of small brightly colored flowers. It is tolerant of poor soils–in fact it prefers sandy or rocky, well drained soils. Hot, dry, and windy places aren’t a problem either. She’s tough! Plant her in full sun and watch her flourish. Will spread up to 2 feet. Not a good choice for clay or poorly drained areas.
