Calylophus drummondianus

Calylophus drummundianus

Belonging to the Evening Primrose family Onagraceae, this “Southern Belle Sundrop”, native to Texas, appears to have the delicacy of a Southern Belle, while being extremely root hardy and drought tolerant. This evergreen, low growing sub-shrub will brighten your garden like a splash of southern sunshine. It thrives in full sun, to part shade and prefers well drained soil. Calylophus grows woody at the base, with herbaceous stems that grow 18 inches tall, and 24 inches wide. The papery, bright yellow flowers bloom almost year-round and are an excellent choice for adding bright pops of color to empty spaces in your landscape.

At home in the prairie grasslands of Texas, Arizona, Oklahoma, and New Mexico, this plant is extremely tolerant of both heat and cold. The Sunset Western Garden zones for Calylophus drummundianus are 1-3, 6-16, and 18-24. This plant spreads by rhizomes and creates a lush carpet of color when planted alongside other Mediterranean climate perennials that have similar water requirements, such as rosemary, sage and lavender. The vibrant yellow flowers will attract birds, bees, butterflies, and other beneficial pollinators to your garden. We are growing Calylophus drummundianus in 1 gallon containers.
