Hypericum elodes

Hypericum elodes, commonly known as marsh St John's-wort, is a low-growing, mat-forming perennial with small, rounded green leaves forming dense mats in wet soils and along pond margins. In summer it produces bright yellow, star-shaped flowers, creating a cheerful display in damp habitats and bog gardens.

This species is valuable for pollinators and contributes to wetland biodiversity, providing nectar and cover for insects. Its creeping, mat-forming habit and tolerance of consistently moist or shallowly submerged soil make it ideal for pond edges, wet meadows, and naturalistic water features.
