Calothamnus quadrifidus Grey

Common Name:
One-sided Bottlebrush 'Grey Form'

Description:
Calothamnus quadrifidus 'Grey Form' is an evergreen Australian native shrub distinguished by its soft, silvery-grey, needle-like foliage and vivid red, claw-like flowers that bloom along one side of the stem. This cultivar offers a striking visual contrast, making it a standout feature in any garden. Flowering occurs from late spring through summer, attracting nectar-feeding birds and beneficial insects. Adaptable to a range of soil types, including sandy, loamy, and clay soils, it thrives in full sun to part shade positions. Once established, it exhibits excellent drought tolerance and can withstand light frosts, making it well-suited to Melbourne's climate. Regular pruning after flowering encourages a dense, bushy habit and prolongs its ornamental appeal.
