There's a lot of this plant at my grandparents place and nobody here knows what it is. It grows from woody bulbs underground and the entire exposed part is the stalk and leaves. They clump together and I suspect they spread by rooting new bulbs underground. The bigger they get, the more red it is at the bottom, and as they approach the bulb it's almost an oniony purple and white. They smell like how you'd expect a garden weed to smell. They can get pretty big, the biggest one being about 45 inches (114 centimeters) tall, though I don't know if they get bigger. Above is a picture of the clump, a picture of the bottom of the big one, a picture of a smaller one (16 inches/40 centimeters) on the table, and grandpa for scale. Location is southeast Kansas.
