Wild quinine

Parthenium integrifolium

par-THEN-ee-um in-teg-rih-FOE-lee-um

Wild quinine bears lustrous foliage and long-lasting white flowers throughout the season, even in heat and drought. It is native to moist prairies, low meadows, and open woods from Massachusetts and Minnesota, south to Georgia and Arkansas.

Noteworthy CharacteristicsGood substitute for Achillea in moist soils. Use as a specimen or filler. Charcoal-gray seed heads can be used in arrangements.

CareAdaptable, but thrives in moist, deep, rich soil in full sun or light shade.

PropagationSow seeds in winter or spring after giving them four to six weeks of cold, moist conditions. Seedlings develop slowly the first year while they establish their tap roots. Plants reach blooming size in two to three years. Can also be propagated from stem cuttings in early June.
