This handsome and hardy shrub and its relatives are widely planted as ornamentals throughout the southwestern U.S. It blooms in response to soil moisture or simply increased humidity, hence its reputation for predicting rain. The dense whitish hairs on its leaves help to reduce water loss during hot, dry weather. Despite its common names, it is not a close relative of the true sages.
