Hypericum forrestii is a species of flowering plant in the family Hypericaceae native to China and Myanmar. It is known as Forrest's tutsan[1] and Forrest's St. John's wort. It was named in honour of the Scottish botanist George Forrest (1873-1932), who was the first westerner to discover it.

Description

It is a semi-evergreen shrub growing to 1.2 m (4 ft) tall by 1.5 m (5 ft) broad. It has oval leaves which turn red in autumn and bowl-shaped yellow flowers with prominent stamens in late summer.[2][3]

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,[4] and as an invasive species.[5] It may be under-recorded due to confusion with other St. John's wort species such as Hypericum 'Hidcote'.[4]
