Hypericum perforatum

Hypericum perforatum, commonly known as common St John's-wort, is an upright, clump-forming perennial with narrow, aromatic green leaves forming bushy foliage. In summer it produces bright yellow, star-shaped flowers with prominent stamens, creating a vibrant display in damp soils, pond margins, and meadows.

This species is valuable for pollinators and supports wetland biodiversity, providing nectar and shelter for insects. Its upright, clump-forming habit and tolerance of consistently moist soil make it ideal for pond edges, wet borders, and naturalistic water gardens.
