Hypericum tetrapterum – Square-stalked St John's Wort

The distinguishing feature of this St John’s-wort is a stout stem with four winged ridges running along its length, hence the common name of square-stalked St John’s-wort, and the more accurate Latin name of Hypericum tetrapterum. Unlike most common St John’s-worts black dots are rare on the leaves and flowers. The pale yellow flowers are out from July to September.
