The Red Cluster Bottlebrush or Callistemon rigidus 'Clemson Hardy' is a blooming shrub that makes a statement all year long. Glossy, oblong green foliage comes to a point and sticks with this evergreen plant throughout the year. During the spring, summer, and fall, clusters of red flowers with thin, wispy petals appear along the branches. The blooms bear a striking resemblance to bottlebrushes and inspire the name. The fuzzy flowers add texture and vivid color to a landscape.
This plant is native to Australia, so that it can live very comfortably in somewhat challenging conditions. In the U.S., the Red Cluster Bottlebrush is a perennial in zones 8 through 11. Established plants are drought- and heat-tolerant and require very low maintenance. Thanks to its bold blooms, this plant is commonly used in a hedge, to create a screen planting, or as an accent. Butterflies and hummingbirds are known to be attracted to this tree-like shrub that is also deer resistant.
Red Cluster Bottlebrush Plant Care
Plant the Red Cluster Bottlebrush in the full sun using well-draining soil. Newly planted Bottlebrush plants need water when the top few inches of the soil dry out. Established plants are drought-tolerant and only need water during an extended dry spell.
Prune in early spring to maintain a neat appearance and promote full and dense growth. Feed the plant using a balanced fertilizer in the spring to encourage more flowers.
Red Cluster Bottlebrush Plant Spacing
This is a large plant and, once mature, Red Cluster Bottlebrush can be 12 to 15 feet tall and 8 to 10 feet wide. When planting with other plants, space everything 4 to 6 feet apart to create a dense hedgerow. Plants can be spaced further apart if you do not want a hedge-like look.

We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
