Kate Brown and Karen Bettink, Thursday 21 December 2017

Alternative Names. African Scurf Pea.

General Biology. Growth form. Shrub/Small tree. Reproduction. Seed. Dispersal. Birds, mammals, water, machinery, ants, soil movement, garden refuse. Time to first flowering. 1-3 years. Vegetative regeneration strategy. Resprouts from base. Seedbank persistence. Soil, long (8 years). Fire response. Fire generally kills mature plants and stimulates germination of soil-stored seed.

Notes. Any disturbance triggers mass germination of soil-stored seed.

Additional information. Origin. Southern Africa. History of use/introduction. Garden escape.

Suggested method of management and control. Hand pull or dig out seedlings or young plants (1- 2 years old). For mature plants cut and paint with 50% glyphosate. Spray foliage of any respouting material with 1% glyphosate. Monitor site for germinating seedlings for at least 8 years. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
