Redbrush is a hardy North American shrub with red or yellow flowers. The scientific name of this plant is Ceanothus sanguineus. There are different synonyms for redbrush, including wild lilac, buckbrush, squaw currant, and snowbrush. The name wild lilac refers to the shrub's lilac-like flowers that are fragrant and attractive to butterflies and bees. The term buckbrush is used because the shrub's branches were used as brooms by Native Americans. Squaw currant comes from the shrub's bright berries that resemble currants. Finally, snowbrush is named after the shrub's ability to retain its leaves even under snowy conditions, hence becoming a valuable source of forage for wildlife in winter.
