Their blue-green colour provides a striking contrast to the brilliant coloration of the flowers. In cultivation, C. phoeniceus is fairly vigorous in its growth habit and will grow in any soil provided ample moisture is available. An open sunny position is preferable and it is tolerant of moist conditions. The plant benefits from light pruning, particularly in the early stages, and this should consist of general shaping and removal of spent flower heads. An application of a complete fertiliser in early spring will encourage new growth.
Propagation is from seed or tip cuttings using new season's growth.
Callistemon phoeniceu s is not affected by frost and no pests have been noted in the Gardens. This is a very attractive shrub that is hardy and easily grown.
