About

Thorncroftia media, the Wolkberg whistlesweet, is an extremely rare species of Thorncroftia, a flowering plant in the mint family, Lamiaceae. It is endemic to South Africa's Limpopo province, where it grows along forest margins on rocky mountain slopes. For 50 years, it was known only from the original gathering in the Wolkberg mountains, but in March 2025, after years of searching, two populations were discovered in highly rugged terrain south-west of the village of Trichardtsdal. It is listed as Critically Rare (Least Concern) by SANBI.
