Plant Profile: Wild Quinine (Parthenium integrifolium)

The hard white flowers are borne in flat topped clusters and resemble pearls. The leaves are coarse and covered by short bristly hairs. The stems are hairy, stiff, and upright so the plant does not flop and need staking. A native of prairies, fields, open wooded areas, rocky woods, and hillsides, wild quinine tolerates both heat and cold well and is easily propagated from seed. It is often used instead of yarrow in moist growing conditions.
