Service Notice

The Western Australian Herbarium’s collections management system, WAHerb, and DBCA’s flora taxonomic names application, WACensus, have been set to read-only mode since 1 October 2025. Recent taxonomic changes are not currently being reflected in Florabase, herbarium collections, or the census. Due to the rapidly approaching holiday season and associated agency and facility soft closures, along with the substantial work involved in data mapping, cleaning, and verification, the migration to the new collection management software is not expected to occur before 1 March 2026, when a further update will be provided. Please reach out to us if you have any questions or concerns.

The notice period started at 9:45 am on Friday, 12 December 2025 +08:00 and will end at 12:00 pm on Monday, 2 March 2026 +08:00.

Prostanthera magnifica C.A.Gardner

Image

Prostanthera magnifica (Magnificent Prostanthera) is part of the mint family (Lamiaceae) and has sweetly scented leaves when crushed. It is an erect, evergreen shrub growing to about 1.5–2 metres high, and as the name suggests, it’s one of the most striking species in the genus. The bright mauve-purple tubular flowers are borne on long terminal spikes and are accentuated by the two large fused red-pink sepals, producing a beautiful, massed display.

The Magnificent Prostanthera prefers granite outcrops and rocky hills from east of Kalbarri to Hospital Rocks west of Menzies. It can be found flowering from August to November.
