Callistemon citrinus, commonly known as Crimson Bottlebrush, is a remarkable evergreen shrub, it captivates with its vibrant, red, bottlebrush-like flower spikes, which bloom intermittently throughout the year, providing a colorful spectacle in frost-free climates. Originating from Australia, this broadleaf evergreen reaches heights of 3 to 5 feet when cultivated in containers in colder climates, and can soar to 15 feet in its natural habitat.
Ideal for USDA Zones 9-10, Crimson Bottlebrush thrives in moist, fertile, well-drained soils under full sun. While it is drought tolerant, it flourishes with regular watering. Its lance-shaped leaves, transitioning from coppery to medium green, release a delightful lemony fragrance when bruised, adding a sensory layer to its visual appeal.
This low-maintenance plant is virtually free from serious pests or diseases, though occasional attention to spider mites and scale may be needed indoors. It makes an eye-catching specimen tree or a charming hedge, attracting bees, birds, and hummingbirds with its abundant nectar. Perfect for city gardens, Mediterranean landscapes, or as a standout container plant, this versatile shrub can also be trained as a small tree up to 25 feet.
Embrace the beauty and elegance of Callistemon citrinus in your garden, where its stunning blooms and enchanting scent promise an awe-inspiring display with minimal effort. Prune after flowering to maintain its shape, and propagate via seeds or semi-hardwood cuttings. Whether as a striking specimen or a vibrant hedge, the Crimson Bottlebrush transforms any space into a vibrant, living tapestry.
