It is ideally suited for coastal habitats and can withstand the challenging conditions associated with coastal Australia.
Cultivation of Callistemon viminalis:
Sunlight: Callistemon viminalis flourishes in full sun, requiring at least six hours of direct sunlight per day.
Soil and Watering: It prefers moist, well-drained soil. While fertile soil is optimal, Callistemon viminalis can tolerate neutral to slightly acidic soil conditions. Adequate drainage is crucial to prevent waterlogging and root rot.
Shelter and Wind Protection: Providing shelter or planting the tree near a wall can help protect it from strong winds and adverse weather conditions.

Callistemon viminalis also includes a captivating hot pink variety, showcasing the stunning color of its flowers. While the species can tolerate temperatures as low as -5˚C (23˚F), it is advisable to provide protection from frost whenever possible.
