Why Doesn't My Bottle Brush Plant Bloom?

Updated July 19, 2017

The bottle brush plant often appears in the landscape in the western United States. Commonly planted in the ground, it also does well in containers and even as a houseplant.


Bottle brush (Callistemon citrinus), a native of Australia, grows best in similar climates. A popular evergreen plant in Southern California and Southern Florida landscapes, bottle brush thrives on bright sunlight, hot temperatures and dry air. It's Cold hardy in U.S. Department of Agriculture plant hardiness zones 9 and 10.


Arranged in a cylindrical shape, the bright red stamens of bottle brush, resemble a bottle brush used for cleaning. A tuft of green leaves grow from the top of each brush. It reaches from 10 to 15 feet when grown in its natural habitat. As a shrub plant, expect it to grow 3 to 5 feet tall.


If your bottle brush isn't blooming, it lacks the right amount of sunshine. Plant it where it receives full sun. If grown as a houseplant, move it to a sunny window.
