Tanacetum vulgare L.

Common Name: COMMON TANSY, GARDEN TANSY
Coefficient of Conservatism: *
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Ad P-Forb

A Eurasian species, much cultivated and widely naturalized, forming large colonies from strong rhizomes. Roadsides, fields, meadows, ditches, shores; vacant lots, farmyards, old building sites, fill, dumps, and other disturbed places; sometimes spreading into open, disturbed forests and clearings, but not doing well in shade. First collected in 1862 in Washtenaw Co. and widespread by the 1890’s.

Like other aromatic plants, this species has been used medicinally. The leaves are ± densely glandular-punctate as well as glabrous and less finely divided than in T. bipinnatum. Our escapes do include a few occurrences of the Fernleaf Tansy, forma crispum (L.) Hayek.
