About Wallum bottlebrush
Callistemon pachyphyllus, commonly known as 'wallum bottlebrush', is an evergreen shrub native to Australia, notable for its bright red, cylindrical, bottle-brush-like inflorescences. It grows 1 to 3 meters tall, with narrow, stiff leaves. It's ideal for coastal gardens, rockeries, or as an ornamental plant in large pots, attracting nectar-feeding birds.
Native range
South-west Queensland and eastern New South Wales, Australia.
Care tips
This plant thrives in full sun for optimal flowering and prefers well-drained, sandy, or slightly acidic soils, tolerating poor nutrient conditions. Watering should be regular during establishment, but once mature, it is very drought-tolerant. Avoid waterlogging, as it is susceptible to root rot. Light pruning after flowering encourages a more compact habit and increased blooms.
