Callistemon subulatus, commonly known as Dwarf Bottlebrush, is an evergreen shrub native to Australia, specifically found in open woodlands and along watercourses in the eastern regions. It typically grows to a height of 1–2 m (3–7 ft) and features hard, fibrous bark with dense foliage. The leaves are narrow, cylindrical, and evergreen, contributing to the shrub’s year-round interest. Dwarf Bottlebrush is renowned for its vibrant, dark crimson flower spikes that appear at the ends of branches, often continuing to grow after flowering. The flowering season extends from spring to summer, with the peak bloom period occurring from November to May in its native habitat. After flowering, the plant produces woody capsules that contain seeds.

The Dwarf Bottlebrush is valued for its abundant and showy flowers, which attract pollinators such as birds and bees. It is a popular choice for urban gardens, borders, and as a specimen plant. This shrub is relatively low-maintenance, requiring minimal pruning and benefiting from the application of low-phosphorus fertiliser to promote healthy growth. It thrives in full sun and can tolerate a range of soil conditions, though it prefers soils with slow drainage. While hardy, it may be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
