Narrative
Erect perennial, 0.4-2 meters tall, arising from a short rhizome. Leaf blades ovate to lanceolate, 4-14 cm long and 1.5-8 cm wide, the apex acute, the margins coarsely serrate, both surfaces covered with rough, siliceous-based hairs or sometimes only slightly rough. Flowers mostly 3-7 cm across on stout naked penduncles, rays dark rich yellow 1-3 cm long, bisexual. The range encompasses the eastern one half of the United States, but its occurrence is not common. Averages 139,000 seeds per pound. A seeding rate of 40 pure live seeds (PLS) in 30 inch rows for seed production is sufficient. Rates for solid seed should be (15 to 25 bulk pounds/acre). Seed should be planted 1/4 to 1/2 inch deep in a firm relatively weed free seedbed. Seedling vigor is good and stands are comparatively easy to establish where competition is controlled. Mowing above its height has been used to reduce competition when weeds begin to severely encroach into the planting. This procedure is probably the best way to control unwanted weed invasion. Seed yields are good and can be readily harvested with a combine. Yields of 250 to 400 pounds per acre have been commonly harvested on managed non-irrigated stands. For isolation requirements, it is considered cross-pollinated. Adapted to soils of a lower fertility level, neutral to mildly acid conditions. Found in open or rocky woods, thickets, prairies, and along railroads. It is found in most counties of the three states served by the Plant Materials Center; Iowa, Illinois, and Missouri. Collections from each zone in Iowa guarantees the adaptaion of releases to the entire zone. The primary purposes of this release are for Iowa roadside revegetation, wildlife plantings, and prairie restoration.
