Water starwort (Callitriche palustris) is an excellent evergreen native evergreen oxygenator which grows underwater and spreads to the surface forming mats of densely packed small green leaves.
Submerged leaves are star-shaped and change to very small rosettes of eliptical leaves on the surface. Starwort gives good surface cover early in the season and produces insignificant tiny white flowers during summer. A haven for wildlife the leaves hold spawn well and is particularly favoured by newts.
We recommend potting bare root in either a 9cm or 1 litre aquatic basket, or planting in the soil of a natural pond. If the pond is sufficiently established with a layer of silt in the bottom it can be weighted down by placing under a stone or aquatic basket. We don’t supply lead weighted bunches as the roots are delicate and do not react well to being tied up with lead. Best grown shallow until fully rooted in its basket and established.
Planting position: Full sun or partial shade submerged in depths from 20cm up to 100cm
Form: Bare root or 1 litre in an aquatic basket
