Yellow St John’s wort flowers
Hypericum species come in all shapes and sizes but they’re all yellow. The herb which is said to improve mood is Hypericum perforatum.
Perforate St John’s wort
This common wildflower grows up to about 90cm and has translucent dots on the leaves and black dots on the petal edges, with flowers 2 to 3cm across.
Hairy St Johns wort
The Hypericum hirsutum I spotted was smaller and more delicate looking. It was growing by the side of a path through woods. The leaves of this plant are more elongated than perforate St John’s wort. The second image shows the hairy stem and stalked black dots on sepals.
