Sizing guide


Callistemon Harkness, commonly known as Bottlebrush, is a striking evergreen shrub that can be grown in gardens and landscapes.

To cultivate this plant, select a sunny location with well-draining soil. Dig a hole twice the width of the root ball and plant the shrub at the same depth as its container.

Water thoroughly after planting and keep the soil moist during the establishment period. Once established, Bottlebrush requires minimal watering. Prune the shrub after flowering to maintain its shape and encourage new growth.

With proper care, Callistemon Harkness can reach a height of 2.4-3mt and spread 1.8-2.4mt. Its vibrant red flowers and unique bottlebrush-like appearance make it an attractive addition to any Australian native garden.
