Ecological significance
The flowers supply moderate amounts of nectar and pollen for insects during midsummer. As a native shrub, it integrates well into local ecological webs. It also engages in arbuscular mycorrhizal symbioses, which can support soil structure and nutrient cycling.
Annual cycle
A deciduous shrub that drops its leaves in winter and flushes anew in spring. Flowers appear in July and August, with fruits and seeds maturing thereafter.

Pflege & Anbau
Grow in partial shade in a moisture-retentive, neutral to slightly acid soil that is not overly rich. Water during dry spells to maintain evenly moist conditions. Little pruning is needed; simply cut out dead or untidy stems after flowering. Avoid excessive disturbance of the root zone.
Scientific profile
Hypericum androsaemum is a deciduous, broad-leaved shrub that typically attains a height of about 65 cm. The plant has a preference for semi-shade and moist, neutral to slightly acid soils of medium nutrient status, and it thrives in relatively warm, low-disturbance situations. It forms arbuscular mycorrhizal associations. The leaves are broad, averaging 675 mm² in area, and the small seeds (diaspores) weigh around 0.07 mg. Yellow flowers open between July and August, contributing nectar and pollen each rated at 3 on a relative scale. Native in Great Britain, the species also occurs in its natural range across Europe.
