Callistemon 'Prolific'

Callistemon viminalis 'Prolific'

ORIGIN: Callistemon 'Prolific' was originally found near Dalby, Qld, by Mr Jim Howie, a nurseryman from Brisbane. It is a form of Callistemon viminalis. It has been in the trade for many years. Registration applied for by the Tree & Shrub Growers of Victoria.

DESCRIPTION: A small tree to 6m high by 4m across with pendulous branch tips. The leaves are narrowly elliptical to 50mm long by 7mm wide. The bright red flowers are borne in spikes clustered near the branch ends. Each spike is about 80mm long by 40mm across. They are seen in late spring and summer and again in autumn in the eastern states and from June to October in Western Australia.

DIAGNOSIS: The only significant differences between this and other forms of C. viminalis are its prolific flowering habit and the flowering spikes borne in clusters at the branch ends. The branch ends are not as pendulous as some forms. It is not readily identifiable.

CULTIVATION NOTES: A hardy small tree. Propagation must be by vegetative means in order to maintain clonal properties. Prune after flowering to maintain habit.
