Non-Native
Stinknet (Oncosiphon piluliferum) is a relatively recent and problematic arrival to Arizona. This plant is spreading rapidly in both urban and wild areas and can quickly dominate a landscape. This little winter annual (6-24 inches) has only recently been recognized as a prolific invasive weed in the Phoenix Metropolitan area and elsewhere in Arizona. The weed has spread from severe initial infestations in Northwest and North Phoenix into metropolitan Phoenix and now has a foothold in Tucson and Ajo. Stinknet is a fast moving invasive in Arizona.
