Discussion

Leucophyllum frutescens is widely cultivated; horticultural varieties differ in habit, vestiture, and corolla color. The plants are cold hardy and can withstand moderate frosts. As in most or all Leucophyllum species, plants usually flower in response to rain.

In Texas, Leucophyllum frutescens is known from much of the southwestern half of the state.
