Calylophus drummondianus (Sundrops) is a native perennial with a wide range, from the Great Plains to southern Canada to northern Mexico. It spreads wide, and is especially lovely grown along walls, in containers, or in rock gardens where it can drape over edges. It attracts butterflies and combines nicely with Lavender, Salvia, Verbena, and Agave. Once established, this plant is very drought tolerant.
