Comprehensive DescriptionRead full entry
This light to yellow green, erect herbaceous perennial can reach heights of about 3 feet. The ovate to lanceolate shaped leaves emerge from a 1 1/4 to 6 inch long stem. Each leaf has a primary mid-vein which is flanked by three subparallel veins. Leaf stems emerge from bulb-like corms which have shallow fibrous roots. Vegetative spread is slow and radial. This species relies on population spread by seed. Independent, single or multiple, whorl branched inflorescence rise from the plant base to a height of 3 1\2 feet. White to pinkish 3 petaled flowers bloom from June to September on compound panicles. Numerous flat, keeled, achenes form terminally in tight rings, mature from July to October. Seedlings will emerge on exposed soils, in stands of existing vegetation or newly disturbed locations.
