Alisma plantago


  Water Plantain

Big spear-shaped leaves and tall stems topped with clusters of white/pale lilac flowers.

Out of stock


Each plant grows from a fibrous root and produces a clump of broad, spatulate leaves with a few tall flower stems topped with pyramid clusters of small creamy pink flowers.

Top tip: Dead head flowers to promote growth.  Vanishes below the soil in Winter, so it’s easier to move new plants in the Autumn or late Spring when the shoots appear.

Flowers: July/August

Height of plant: 20-60cm from crown with spears of flowers held well above the foliage.

Propagation: Self sets from seeds.

How to plant:  Plant into a 5lt planting basket using heavy garden loam or Westland Aquatic Soil and place on a shelf in the pond. Fill the planting basket with soil so that the crown of the plant – from where the roots grow down and the shoots grow up – is level with the rim of the basket. Hold the plant securely and fill in with soil all around the roots, press the soil down very firmly but being careful not to damage any new shoots. Fill the planting crate to just below rim.  For aesthetic purposes, the soil can then be top dressed with no more than 1cm of pea gravel.

Recommended planting depth:  Position on the shelf so that the soil in the basket is 5-20cm below the water surface. The planting depth is always measured from soil surface to water surface, not including any gravel top dressing. Raise the basket on slabs or bricks to achieve the recommended planting depth.
