The Red Cluster Bottlebrush (Callistemon citrinus or Melaleuca citrina) is a vibrant, fast-growing ornamental tree or large shrub, best known for its bright red, brush-like flowers that light up the landscape. Native to Australia but widely used in South Florida and other warm regions, this plant gets its name from the cylindrical flower spikes that resemble old-fashioned bottlebrushes. It’s a standout choice for gardens that aim to attract birds, bees, and butterflies—all while delivering a bold pop of color.

Typically growing 10 to 20 feet tall, the Red Cluster Bottlebrush can be pruned into a small tree or kept shrubby and dense. Its narrow, evergreen leaves have a fresh, lemony scent when crushed, and its vibrant red flowers bloom profusely, often multiple times a year in warmer climates. The showy blooms are made up of hundreds of tiny flowers packed into long, brush-like spikes that look striking against the green foliage.

This plant is drought-tolerant once established, can handle salty breezes, and thrives in full sun. Its low-maintenance nature and flair for attracting wildlife make it a favorite for residential yards, pollinator gardens, and street plantings.

Fast Facts

Bloom on Repeat

This plant doesn’t just bloom once and done—under the right conditions, it can flower several times a year. Each burst of fuzzy red blooms draws pollinators like magnets and turns the whole plant into a traffic stop for hummingbirds and bees.

Hometown

The Red Cluster Bottlebrush is native to the coastal regions of eastern Australia, where it thrives in sunny, well-drained areas. Its adaptability and love for heat made it a natural fit for Florida’s subtropical climate.

Bird Feeder in Bloom

Hummingbirds and nectar-loving birds adore the Red Cluster Bottlebrush. Its tubular flowers are a built-in buffet, making it a perfect pick for anyone wanting a lively, bird-friendly garden.
