Hypericum kouytchense |
Hypericum kouytchense, the large-flowered St John's wort, is a species of flowering plant in the family Hypericaceae, native to Western China. Growing up to 3 ft (0.91 m) tall and 5 ft (1.5 m) wide, it is a semi- evergreen rounded shrub with blue-green leaves and large yellow flowers with prominent stamens, appearing in midsummer. [3] Flowers are followed by red seed capsules in autumn. Where conditions are favourable it can retain its leaves all year.
The Latin specific epithet kouytchense is a westernisation of Guizhou, [3] a southwestern province of China identified as a hotspot for biodiversity.
This plant, which is hardy down to −15 °C (5 °F), is cultivated in temperate regions. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit. [4] [5] It has been reported as invasive in Hawaii. [6]
