This broadleaf evergreen with distinctive flowers is grown as a large shrub or small tree in warm areas. Bottlebrush typically reaches 8 to 15 feet tall and wide. For small spaces, try Dragon Fire, which only reaches 3 feet tall and wide.
Northern gardeners can grow crimson bottlebrush in a container outdoors and overwinter it in a sunroom or greenhouse, since the plant is cold hardy down to 20 to 25 degrees. It’s resistant to most diseases, and deer usually don’t bother it. When growing this plant indoors, keep an eye out for spider mites and scale.

Plant bottlebrush in full sun (six to eight hours of consistent sunlight) in Zones 8 to 11. It’s not too picky about the soil it’s planted in, but it grows best in acidic, moist soils with good drainage. It also prefers to have consistent moisture when first established—so remember to keep it watered!

Crimson Bottlebrush Shrub Benefits
There’s a good reason crimson bottlebrush appears frequently in southern landscapes; it’s incredibly heat-tolerant. This shrub will bring pollinators such as native bees and birds into your backyard. Hummingbirds, especially, love the red flowers!
In addition, its blooms delight intermittently all year in warm regions. Even better, the crimson bottlebrush generally doesn’t require a whole lot of maintenance; prune in early spring or late summer. Gardeners appreciate the shrub’s showy blooms, but the foliage’s coppery-green leaves add interest, too. Leaves have a lemon fragrance when crushed.
