Stinknet: a Weed Advancing in Southern Arizona

By:
Michael Chamberland

Stinknet, also known as globe chamomile, is a relatively new weed in Arizona that has quickly spread.  The first herbarium collection for Arizona was made in the spring of 1997 and the first published account of its presence in Arizona was by Landrum et al. (2005).  By 2019 the plant had risen to public attention due to its conspicuous presence.  Stinknet is now common in the Phoenix metro area and across much of Maricopa County.  It is spreading south along the I-10 corridor, becoming well established in Pinal County.  Outbreaks have occurred within the Tucson metro area, and also in rural parts of Pima County.  Recent observations show stinknet has found its way into Mexico (SEINet Portal Network, 2020).
