Artemisia campestris L.
Common Name: WILD WORMWOOD
Coefficient of Conservatism: 5
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Nt B-Forb

Sand beaches and dunes, gravelly and rocky shores; sandy oak and jack pine savannas; sandy fields, roadsides, railroad ballast, river banks, and prairies.

There is great diversity in size of heads, nature and distribution of pubescence on the leaves and involucres, degree of lobing of the leaves (although the lobes are always very long and narrow), and the nature of the inflorescence, often a large terminal panicle with hundreds of heads. Our plants are apparently all subsp. caudata (Michx.) Hall & Clements.

The foliage is scarcely if at all aromatic, and variable as to pubescence. Collections with both involucres and leaves densely silky have been noted from Antrim and Keweenaw Cos.
