  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. 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: Best planted between mid-February and mid-September, the plant derives all its nutritional needs from the pond water so there’s no need to feed. If this plant becomes untidy, give it a light trim to shape.
