T he stems of limnophila can grow to 12 feet long, with a few inches being emersed above the water. The emersed leaf margins appear to be torn irregularly. The submersed leaves are very different looking, being finely divided and feathery, about one inch long, and in whorls about the stem. Limnophila flowers are not common. They are blue, violet, pink, or lavender.
Single flowers grow on the emersed part of the stem.
