Horticulture

Baja California fairy duster is widely planted as an ornamental shrub in warm areas of Arizona. The showy flowers attract hummingbirds and butterflies. The plants flower nearly year-round with warmth and moisture. Established plants are drought tolerant but require regular irrigation during hot weather to maintain an attractive appearance. The plants are hardy to 25° F (-4° C). Frozen plants recover rapidly the following season. Frozen stems may be pruned and the plants can be pruned to control size but otherwise require little maintenance. Litter is minimal.
