Also known as Banana Lilly because of its banana shaped roots that store nutrients. Varieties are numerous, producing yellow or white flowers. Leaves are small and resemble a heart with a notch where the stem attaches. It is often mistaken for a miniature water lily.

It grows rooted or as a floating plant and can quickly fill a pond in a couple seasons. Leaves are green above the water and a dull purple below.

Due to its high rate of growth and invasive habits it is VERY difficult to control. Plan on a long term program for control.
