There are several species of Callistemon that will grow in Louisiana, but in my opinion the eye-catching lemon bottlebrush is the most tolerant of temperature extremes and poor soil. The large, red, bottlebrush-shaped flowers attract bees, butterflies, hummingbirds, and nectar-feeding songbirds such as orioles and prothonotary warblers.
Bottlebrush is an excellent specimen shrub in hummingbird and pollinator gardens, especially in the Coastal South. In North Louisiana, it should be given some winter protection. Callistemon will not tolerate heavy, poorly drained soils. Propagate by stem cuttings of semi-ripe wood in summer. Seed culture often produces variable plants.
Good companion plants include coral bean (Erythrina herbacea), Turk’s cap (Malvaviscus arboreus var. drummondii), Indian shot canna (Canna indica), butterfly ginger (Hedychium coronarium), and various Salvia.
