There are about 40 species of naiads in the world. The stems are very long and have many branches. Leaves are deep green to purplish green and very narrow and short. Reproduction occurs from seed and fragmentation of the brittle branches.
Naiads prefer warmer water and grow at an astounding rate. Plants can bloom into giant bushes and even after treatment reappear several times in a season. Spreads like wildfire in the warm months.
Chemical control is effective but this plant can return fairly quickly after treatment.
