Hypericum henryi subsp. hancockii ‘September Sun’

A particularly graceful, airy species I found half way up Tay Con Linh mountain in N. Vietnam, virtually on the Chinese border. Dainty, bright-yellow flowers over an exceptionally long period in late summer/early autumn and attractive, small, narrow leaves, all on a shrub up to 2m high in the wild, with arching narrow stems. This clone received an AGM in the RHS trial recently and was named here. An exceptional Hypericum.
