Distribution
Forrest's St. John's wort is native to Yunnan and Sichuan provinces in China, and northeastern Myanmar. It has been recorded as a garden escape in locations in the British Isles,[5] and as an invasive species.[6] It may be under-recorded due to confusion with other St. John's wort species such as Hypericum 'Hidcote'.[5]
