Potentilla palustris, also known as marsh cinquefoil or bog strawberry, is a British native found growing naturally alongside ponds, streams and ditches. It has strawberry-like leaves and wine-red, star-shaped flowers in early summer, which are very attractive to butterflies, bees and hoverflies.
As its common names suggest, Potentilla palustris likes wet conditions – plant in a bog garden or at the edge of a pond. It will gradually spread, shading the water.
Plant Potentilla palustris near the edge of a pond in an aquatic basket containing aquatic compost, with around 10cm of water over the top of it. Alternatively, plant in a bog garden or in a pond in a pot.
