Fringe lily (Nymphoides peltata), also known as Yellow floating heart, has leaves that look like miniature water lilies and yellow fringed star-shaped flowers held above the water from July to October.  A very vigorous grower which will soon provide a dense covering in new ponds which is useful for keeping water clean and helping to control algae.  It sends out runners which produce new attached plantlets along their length and whilst easily contained by trimming back you should be wary in larger ponds if you don’t want the maintenance overhead.   A very useful native plant for providing shade and shelter for fish. Not recommended for Ireland where it is considered an invasive non-native species, although not banned for sale there.
