Crex Sand Prairie State Natural Area, Burnett Co., WI
I couldn't get closer than 10 ft because of fear of ticks. Couldn't get a good pic of the stem.
ALST: Prairie onion
Allium stellatum (Autumn onion, Prairie onion) is a perennial wild onion native to North America, where it grows in rocky, sandy soil. It grows from a bulb to about 1-2 feet (30-60 cm) with tufts of leaves which die back as the scape of pink to purple flowers forms. The bulbs are strongly flavored but can be eaten.
