Description:	In 1996, the USDA-Natural Resources Conservation Service (NRCS) Jamie L. Whitten Plant Materials Center (PMC) released three locally collected, source-identified wetland plants. Indian Bayou source powdery thalia (Thalia dealbata Fraser ex Roscoe) and Leflore source creeping burhead [Echinodorus cordifolius (L.) Griseb.] were collected in the Mississippi Delta and Leaf River source woolgrass [Scirpus cyperinus (L.) Kunth] from southeastern Mississippi. Both vegetative propagules and seedlings can be planted. PMC seed-germination studies have shown that Indian Bayou and Leaf River germinate readily after exposure to cold, moist conditions (stratification). Indian Bayou germination and seedling growth was best in a moist, not saturated, growing medium, whereas best germination of Leaf River was in a saturated medium, and seedling growth was better in a moist medium. Germination of Leflore was very poor for all seed treatments in the test, even though seedlings have established in PMC plant-production ponds.
