Water wisterias have stiffer stems and leaves than water sprites. If you take the plant out of the water, water sprite leaves will often fold upon themselves and bruise easily while water wisteria leaves can still hold their own shape out of the water. This only applies to the broad leaf variety of water sprite which used to be everywhere in the hobby decades ago. I hardly see any now. This plant is another one that will grow like a weed if the conditions are right.
