Description
Alisma plantago-aquatica forms pleasing drifts of broad grey-green lanceolate foliage. Throughout summer, a profusion of tall stems bear airy panicles of small white or pink flowers. This marginal aquatic thrives in boggy soil or the shallow margins of ponds. Water Plantain is a hardy perennial British native making a useful contribution to wildlife ponds. Height: 90cm (36"). Spread: 45cm (18"). Planting depth: Zone 1 & 2 to 15cm below water level.

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Plant Alisma in boggy soil or submerged in the shallow margins of ponds, to a maximum depth of 15cm (6") below water level. Choose a position in sun or semi-shade.
More Info
Alisma seeds about freely. Remove the faded flowers before they set seed to encourage more blooms to be produced and to prevent self seeding. Cut back the old foliage in Autumn.
