The award-winning and native bog pimpernel forms a dense carpet of semi-evergreen leaves peppered with fragrant, tiny rose-pink flowers from June to September.

Anagallis tenella makes a great addition to the margins of any pond, bog garden or very shallow water. This pretty, low maintenance aquatic plant requires little trimming and is disease resistant.


  • Garden care:
    Plant in shallow water (0-10cm or 0-4in) or very damp soil at the pond edge. It prefers full sun and naturally low-nutrient, acidic to neutral conditions. The plant feeds from the pond water, so no additional fertiliser is needed.

    It spreads low and mat-forming, making it good for soft edging—trim lightly if if it becomes straggly or overgrown. Keep moist at all times, as it will quickly decline in dry soil.
