Gratiola officinalis

Gratiola officinalis, commonly known as common hedgehyssop, is a low-growing, creeping perennial with slender green stems and small, lance-shaped leaves forming mats along damp soils and pond edges. In summer, it produces tubular, pale lilac to pink flowers with darker throats, adding a subtle, delicate floral display in wetland plantings.

This species is valuable for pollinators and contributes to biodiversity in damp habitats. Its creeping habit and tolerance of consistently moist soils make it ideal for pond margins, bog gardens, and naturalistic water features.
