Description
Bottle Brush (Callistemon spp.), commonly known as Red Bottlebrush or simply Bottlebrush, is a distinctive evergreen shrub or small tree admired for its vibrant, bottlebrush-shaped flowers in shades of bright red, pink, or sometimes yellow. Native to Australia, this plant produces dense, cylindrical flower spikes that resemble a bottle brush, giving it its common name. These striking blooms typically appear from spring through summer and attract pollinators like hummingbirds, bees, and butterflies, adding lively color and activity to gardens.
Bottle Brush grows to about 5 to 15 feet tall, though some varieties can reach up to 20 feet or more, depending on the species and growing conditions. This plant thrives in full sun and is hardy in USDA zones 8-11. It adapts well to a range of soil types, including sandy and loamy soils, as long as they are well-draining, and is drought-tolerant once established. Bottle Brush also tolerates coastal conditions, making it an ideal choice for coastal or Mediterranean-style landscapes.
Generally low-maintenance, Bottle Brush benefits from occasional pruning after its blooming season to maintain shape and encourage bushier growth. It’s also resistant to pests and diseases, making it a resilient option for various climates. Used as a focal point, hedge, or accent shrub, Bottle Brush brings a unique, exotic look to landscapes with its unusual flower form and vivid colors, adding year-round interest to both formal and naturalized garden designs.
