Banksia grandis: is a member of the Proteaceae family and is a native of
Western Australiawhere the species is found in the south west corner of the State.
Bull Banksia is the common name of this large shrub or small tree. The bark is rough and grey in colour. Large leaves are divided into triangular segments. Young growth may be bright red. The cylindrical flower heads are up to 40 centimetres long by 10 centimetres wide. The flowers are greenish-yellow aging to bright yellow. The cones, that follow the flowers, are large, dense and have many follicles (a dry fruit holding two winged seeds). Cones are sometimes cut into slices and used as drink coasters.
Plants may take many years to mature and flower. In the interim you will be able to admire the attractive foliage.
Banksia grandis appreciates well-drained soils in either full sun or dappled shade. The species should tolerate frost.
The plant illustrated is growing in one of the gardens at Yallaroo. This specimen is about two years old (summer 2005) and in the spring of 2005 put on nearly 30 centimetres.
As with most Banksias we suggest that plants are well-watered during dry periods.
The Bull Banksia was first cultivated in the
in 1794. The species was named from a plant cultivated in United Kingdom Europe. It is thought that this plant was raised from seed collected in Western Australiain 1791.
Propagate from seed and be prepared for a lengthy wait before the plants flower.
