Ecological significance
Being a native wildflower, hairy St John’s-wort supports local insect populations by providing a reliable source of nectar and pollen during the summer months. It is not invasive and blends well into naturalistic plantings.
Annual cycle
Fresh growth emerges in spring. Flowering takes place from June to August. Seed ripens in late summer and early autumn, and the above-ground parts die back by winter. The plant stays dormant underground until the following spring.

Scientific profile
Hairy St John’s-wort (Hypericum hirsutum) is a non-woody, herbaceous perennial that reaches a height of around 60 centimetres. It has broad leaves and occurs in tall-herb communities on fresh, base-rich and often calcareous soils, usually in sites with partial shade or dappled sunlight. The plant flowers from June through August, with blooms that supply a moderate level of both nectar and pollen to visiting insects. It dies back to ground level in autumn, overwintering as a rootstock.
