Abronia–commonly called sand verbena–is a trailing perennial or annual that bears dense, verbena-like round-topped clusters that can be pink, rose-pink, or purple. Abronia resembles verbena but is not a true verbena.
Abronia is a perennial in mild-winter regions of the Western United States where it is a native. It can be grown as an annual where winters are cold.
Low-growing Abronia is an effective edging for walkways and borders. Because it trails, Abronia can be used in hanging baskets or window boxes or as a potted plant near the edge of balconies. Abronia can be grown in seaside gardens in sandy and dry soil.
Abronia is a genus of about 35 species native to Arizona, Nevada, Southern California, and Baja California.
