Pine-leafed bottlebrush, as the name suggests, has needle-like leaves resembling pine foliage. This rather upright shrub is native to southeastern Australia. It is rather uncommon in cultivation, at least in the southern U.S. This species occasionally has red bottlebrush-like flowers but more often the flowers are green. We obtained it as Callistemon viridiflorus, another species with green flowers. It should have a sunny or semi-shady location with well-drained but moist soil. Some botanists consider this to be a Melaleuca rather than a Callistemon.
