Chasmanthium latifolium (Uniola latifolia)
Part sun to light shade, moderately wet to medium moisture level, tolerant of poor soils but prefers fertile soils, acidic to neutral pH. 3-4 feet height, blooms in fall, green flowers, will self-seed and may become aggressive under its preferred conditions.
Germination Code: C(60)
Native Region: Statewide
Warm-season, clump-forming grass that is both low maintenance and highly ornamental. Distinguished by the flat, drooping seed heads that hand in terminal clusters up to 10 inches long, which are initially green and turn straw-colored as they ripen. Good accent plant for open woodland gardens. Dried plants and seed heads are popular for cut and dried arrangements. Grows best on deep, moist well-drained sites. Prefers shade but can tolerate full sun with more water.
