Chenopodium bonus-henricus R. W. Smith

A locally occurring introduction from Europe, sometimes grown as a potherb and spreading to disturbed ground. Collected as early as 1875 in Genesee Co., but not since 1937.

The small heads of flowers are ± closely crowded in a terminal spike, while in C. rubrum the heads are more distinctly axillary or in axillary spikes. This is our only perennial Chenopodium; the stems forming a clump from stout roots.
