Banksia sphaerocarpa is a shrub that can grow between 3′ and 9′ feet tall and 6′; to 12′ wide. The leaves are narrow and linear. The inflorescences occur on short lateral branchlets. They are yellow-brown to orange in color.
The species are quite variable and at least three varieties are recognized – var. sphaerocarpa, var. caesia and var. dolichostyla:
- var. caesia – larger growth habit than the type and with glaucous (greyish) leaves and smaller seed follicles.
- var. dolichostyla – also with glaucous leaves and small seed follicles but with longer flower parts (perianth and style) than the other varieties.
This species develops a lignotuber and can regenerate by vegetative means from the lignotuber if the upper parts of the plant are destroyed by fire.

Banksia sphaerocarpa is native to Australia.
Propagation from seed is said to be reliable without pre-treatment. I haven’t tried that.
Cuttings are said to be slow to strike and success rate may be well below 100%.
