Plant of the week - Monarto mintbush

Date posted: 24 July 2014

This week’s plant of the week is the Monarto mintbush (Prostanthera eurybioides), a very important species not just in our state but nationally. Endemic to South Australia propagation of this rare plant has been limited due to poor germination. It has been listed as endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

The South Australian Seed Conservation Centre (SASCC) located in Adelaide Botanic Garden carried out a germination trial working alongside the Mount Lofty Botanic Garden Nursery. This collaboration saw the SASCC successfully germinate Monarto mintbush seeds which the Nursery was able to grow. The germinated seedlings will be planted in the wild where the species naturally occurs, boosting numbers.

To date 400 endangered Monarto mintbush plants have been propagated by the Nursery and planted at Monarto where the species is endemic.

Did you know?

The propagation of rare, threatened and endangered species is a very important role of the Botanic Gardens of South Australia. Together the Nursery and the South Australian Seed Conservation Centre collaborate on a range of projects with a variety of plant species. The skills and expertise of the SASCC and the Nursery come together to conserve threatened plant species in-situ.
