Description
  • Woody perennial many-branched shrub 3m or more, from the Mediterranean, forming dense thickets like Scotch Broom.
  • Leaves are small and have three leaflets. They are larger, softer and much more profuse than those of Scotch Broom. The plant remains green and leafy throughout the year.
  • Yellow pea flowers are smaller than Scotch Broom but very numerous, in clusters on the ends of the branchlets. Main flowering spring and summer; some flowers most of the year.
  • The seed pod is smaller than that of Scotch Broom, brown and densely hairy. Seeds are hard, black and shiny.
Dispersal
Large numbers of long-lived seeds are spread by water, animals, mud on shoes or tyres, or in contaminated soil.
Impact on Bushland
Like Scotch Broom, Cape Broom spreads rapidly, grows in any soil, forms thickets, reduces biodiversity, and changes soil chemistry. Fire stimulates seed germination.
Distribution
Throughout the Blue Mountains.
Alternative Planting
Bush Peas (Pultanaea species) 60cm to 4m; Pea Flowers (Dillwynia species) to 2m; Logania (Logania albiflora) 2m. See also suggestions for Scotch Broom.
Control
Do not mow or slash. Spray, dig out or cut and paint when pods are green. Expect to hand-remove seedlings for years.
