Water plantain (Alisma plantago-aquatica) is a pretty British native plant with dainty white flowers from June to August/September which tower above it’s foliage. Remove the seed heads to avoid self seeding. Sun or part-shade. Please note when these get larger from May onwards their foliage is easily damaged so bent or broken leaves are difficult to avoid no matter how carefully we pack them! Remove any broken leaves and they will soon be replaced.
Planting position: Pond marginal shelf up to 40cm deep; or very wet soil.
