PIMA COUNTY, Ariz. — Staff from Pima County Departments are working with Arizona Native Plant Society to fight against an invasive plant that has taken over large hay area in Maricopa County.

The plant called Oncosiphon piluliferum, also known as Stinknet is a yellow globe-like flowers with a green stalk, according to Pima County officials.

Pima County says the native South African plant is considered to be intrusive and will soon be classified as an Arizona poisonous weed.

The Stinknet began generating in 2015 near the west end of Prince Road then began to spread across the roadway to the Chuck Huckelberry Loop between UArizona Farm and Rudasill Road.

The plant generates, grows and spreads faster during the winter season causing allergic reactions from the pollen.

Pima County Regional Flood Control District and volunteers with Arizona Native Plant Society started to kill a small outbreak this spring 1-10 and Prince Road.

Stinknet identification sessions will be offered through Pima County and the Arizona Native Plant Society from 10 a.m. and 2 p.m. this Thursday, Dec. 12, and again on Thursday, Dec. 19. adjacent to the Inland Kenworth business property.
