WILD LICORICE - Glycyrrhiza
lepidota (Nutt.) Pursh
Fabaceae - (Pea family)
Wild licorice is a perennial reproducing from deep, spreading roots or seeds. Stems 1 to 3 feet tall, erect, simple or with upper part producing erect branches. Leaves alternate, pinnately compound with 11 to 19 deeply veined lanceolate leaflets with glandular dots when mature. Flowers in short axillary spikes on long peduncles; calyx with 2 upper teeth shorter and partly united; corolla with narrow standard and blunt keel, green-white to white, stamens - 9 fused by filaments and 1 separate. Seed pod about 1/2 to 3/4 inch long, burlike, covered with stout, hooked prickles; seeds to 1/10 inch long, bean-shaped, reddish-brown, smooth and dull.
Wild licorice is a widely distributed native plant commonly found in moist, sandy soils of meadows, pastures, prairies, ditch and river banks and waste areas. The common licorice used to flavor candy is a different species, though the root of wild licorice is equally sweet and was an important food source for Native Americans.
Non-standard name: American licorice.

Licorice can be controlled with Transline at 1 pint per acre. This plant is very resistant to herbicides, but clopyralid, the active ingredient in Transline, Redeem, Curtail, Widematch, and Stinger, is very effective.
