Welcome to Arizona Native Plant Society

Our mission is to promote knowledge, appreciation, conservation, and
restoration of Arizona native plants and their habitats.


Our goal is to help you select local plants that are both beautiful and economical while thriving in our natural habitat. This will result in plants that are easier to care for and better support our local ecosystem. Our Grow Native initiative is here to help show you the way!

Stinknet continues its explosive spread in Arizona!

Following a wet 2019 winter, we experienced a wet 2020 winter. This has resulted in yet another explosion of Stinknet (Oncosiphon pilluliferum) in Maricopa County and further incipient outbreaks in Pima County. State agencies and the public need to become aware of this very noxious weed and snuff it out wherever it shows up.

Our stinknet brochure was recently updated (Feb 2020) and is available in English and Spanish.

Arizona Noxious Weed list is finally updated!

The updated Arizona State Noxious Weed List was approved through the governor’s office and became law on January 4, 2020. The last prior update was made in 2005. Several species have been dropped from the old list and many new ones have been added.

The Arizona Native Plant Society and the Southwest Vegetative Management Association (SWVMA) partnered to do the research and finalize the new list, to lobby the Department of Agriculture, and engage in active advocacy in public meetings. Thank you everyone for your efforts!
