Young plant

Stinknet is a fast-moving, invasive weed in Arizona. It has green “carrot like” leaves and rounded flowers. The leaves smell pungent. It can be allergenic. It emerges from November to April and starts flowering in February. Seed is easily spread by wind and traffic. It loves to sprout in the stones along the cement before the blacktop and also in driveway cracks. If you do not get rid of it, it will sprout all over our yards and into the desert.
When it easily seeds into our Sonoran Desert, it crowds out native plants and rows in mats that are highly flammable during our hot summers. Also, it will spread very quickly all over your (and the neighbors’) gardens. Please remove this noxious weed if you find it in your yard. Do not be fooled by the bright, round yellow flowers. Be vigilant and eliminate it.
