Most of these cultivars have arisen as chance seedlings rather than by deliberate hybridisation. In general, C.citrinus is a medium shrub reaching about 2m by 2m. It is a hardy plant under a wide range of conditions. Many Callistemons can tolerate less than perfect drainage but usually perform best in gardens with reasonable drainage and regular availability of water. Callistemons respond to well to annual fertilising after flowering and are not as sensitive as some other Australian plants to phosphorus.
Propagation is easy from both seed and cuttings.
However, propagation of named cultivars must not be carried out from seed because of seeding variation that occurs. You may have reached this description from one of several different sources.
