About

Leucophyllum frutescens is an evergreen shrub in the figwort family, Scrophulariaceae, native to the U.S. state of Texas, where it is the official "State Native Shrub of Texas", and to the states of Coahuila, Nuevo León, and Tamaulipas in northern Mexico. Although commonly known as Texas sage, it is not a true sage and is distinct from the genus Salvia. The species is also called Texas Ranger, Texas rain sage, cenizo, Texas silverleaf, Texas barometerbush, ash-bush, wild lilac, purple sage, senisa, cenicilla, palo cenizo, or hierba del cenizo.

How to grow it

It requires minimal water, is easily shaped into hedges, and blooms over the entire surface. It is available in a variety of cultivars, including 'Green Cloud', 'White Cloud', 'Compacta', 'Convent', and 'Bert-Star'.
