Over-the-counter deer firearm permit sales begin on Tuesday, Oct. 20. Due to recent software updates beyond IDNR’s control, some vendors may have limited availability to print permits and licenses. IDNR is working closely with the license system provider to quickly address the issue for those vendors.

Features and Behaviors

FEATURES
Woolly milkweed grows to a height of less than one foot. Leaves are arranged alternately along the stem. Seedpods grow to about four inches in length. Flowers are positioned at the stem tip and are pale green in color, sometimes with purple on the back.

BEHAVIORS
Woolly milkweed flowers from May through June. It is found in the northern one-sixth of Illinois. Woolly milkweed grows in rocky or gravel prairies where it reaches its eastern range limit. Its populations have been reduced by overgrazing and gravel mining, and it is endangered in the state.
