Artemisia caudata flowers

Flowering - July - October.

Habitat - Sand and gravel bars along streams, sandstone glades, bluff escarpments.

Origin - Native to U.S.

Other info. - This weedy looking species can be found in just a handful of Ozark counties. The plant can get quite large when left untouched and is a biennial or short-lived perennial. This is an easy species to identify in the field because of its clusters of pinnately divided leaves at each node, and its small but numerous flowerheads. At anthesis the entire plant seems covered in flowers. Unfortunately, the pollen is a major cause of hay fever in the fall.
