Description:
common name for the Pontederiaceae, a family of chiefly tropical perennial aquatic herbs found in freshwater. The pickerelweeds (genus Pontederia ) range north into temperate regions, including most of the E United States and Canada. The water hyacinth ( Eichhornia crassipes ), a native of tropical America, has spread widely and is so prolific that it has clogged many waterways in the S United States and in other countries, including Java and Australia. It is sometimes cultivated in tanks and ponds for its ornamental foliage and blue-violet flowers. The pickerelweed family is classified in the division Magnoliophyta , class Liliopsida, order Liliales. (from encyclopedia.com)
