In the seed oil, linolenic acid and glycerides predominate. Germplasm Reported from American, African, and Eurasian Centers of Diversity, cattail is reported to tolerate poor soil and waterlogging. Distribution Typha latifolia is the common inland species in the USA, inhabiting marshes, shallow water, ditches, and wet wastes along river. It is said to be native throughout the United States, Eurasia, and North Africa. Cultivation Not currently cultivated, but could be considered as a cultivar for ornament, food, or medicine by those disposed to use the plant.
Propagation is usually by division, but the minute reed can be planted in pots in water.
Harvesting If the rhizomes are to be harvested for energy or food, it is suggested that fall might be the best time for harvesting. While I believe these figures are extremely optimistic, I would endorse a serious study of cattails as a potential energy source. Douglas Pratt is quoted in the Washington Star to recommend several advantages to cattails. Since they grow in wetlands, cattails do not compete for land that could be used for crops or forests, and drainage is unnecessary. Cattails use some pollutants as nutrients.
