Smooth Frogbit (Limnobium laevigatum)
The roots of this floating plant help to remove nitrates from the pond and the leaves offer great shelter for small wildlife and fry, as well as helping to prevent algae. Smooth Frogbit has shiny green leaves which are filled with a spongy tissue to aid buoyancy. New plants are formed on the end of runners. Also known as West Indian spongeplant, South American spongeplant or Amazon.
Caution: Not Hardy, bring inside if there is risk of frost.

Specific Plant Care:
Not hardy. Remove decaying plants after first frost. To overwinter, place in shallow water with a little soil for the roots to grow into. Keep in good light at above 10 °c. Return to the pond late April - May when there is no risk of frost.
Just place the plant on the surface of the water. These plants are best brought inside as the nights start to get colder during very late summer to protect them from frost.
