Why grow lesser water-plantain?

It is a declining native plant, listed as Near Threatened on the GB Red List. Growing it in a wildlife pond helps keep a scarce wild flower in cultivation.

Where to plant it

  • The very shallow edge of a wildlife pond, 1–5 cm deep
  • Small ponds and container ponds, where its small size suits
  • A sunny spot in full sun

How to plant and care for it

Plant in spring or summer in full sun with 1–5 cm of water over the crown. Trimming off spent seed heads can bring a further flush of flowers.
