Service Notice

The Western Australian Herbarium’s collections management system and census were set to read-only mode on 1 October 2025. Taxonomic updates published since this time are not being reflected in Florabase, herbarium collections, or Western Australia’s taxonomic names census (Nomos). Conservation listings displayed on Florabase may also be out of date. Please refer to DBCA’s Threatened species and communities webpage for the most recent Threatened and Priority Flora List, noting that recent taxonomic updates are similarly not included. Our database migration is moving to a staging phase. We thank you for your patience as we ensure the integrity of our biodiversity data, develop new workflows, and train staff to use the new systems. Please reach out to us if you have any questions or concerns.

The notice period started at 12:00 pm on Wednesday, 1 October 2025 +08:00 and will end at 12:00 pm on Friday, 1 January 2027 +08:00.

Management Notes (for the Swan NRM Region)

General Biology. Growth form. Vine. Reproduction. Seed. Dispersal. Explosive, birds, water, soil and garden refuse. Time to first flowering. 2+ years. Vegetative regeneration strategy. coppices/resprouts. Seedbank persistence. Soil, medium, 1-5 years. Fire response. Fire can kill mature plants and stimulate seed germination.

Notes. Infestations smother all ground-flora, topple shrubs and trees and prevent any regeneration occurring. Soil disturbance generates mass seed germination.

Additional information. Origin. South Africa. History of use/introduction. Garden escape. Similar native species. Hardenbergia comptoniana.

Suggested method of management and control. Hand pull seedlings and small plants ensuring removal of all root material; sever vines of larger plants and leave to dry in canopy, then dig out woody roots; scrape and paint using 100% glyphosate or foliar spray in highly degraded sites with 1.5% glyphosate; in more sensitive sites, cut stems off at chest height, lay lower sections on ground and apply 1.5% glyphosate over them. 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.
