Seeking native plants to use in landscaping?

Native Landscaping Plants

If you would like to learn which plants are native to our area, we invite you to view our Chapter’s List of Recommended Native Landscaping Plants (draft version). It highlights plants that are: 1) native to the Phoenix metro area, 2) beneficial to wildlife, 3) low-water-use, 4) relatively easy to care for, and 5) generally available at local nurseries or seed suppliers.

The AZNPS Grow Native resources provide additional information about landscaping with native plants, including planning your garden and pamphlets available to download.

Local Nurseries & Plant Sales

We’ve compiled a list of metro Phoenix nurseries that generally offer a selection of native plants. Some have more variety than others, and inventory changes frequently or may be seasonal. So, it is best to inquire with a few nurseries by phone or email to determine which one suits your needs.

In addition, several organizations hold desert plant sale fundraisers in the Spring and Fall. We’ll update this announcement if/when additional native plant sales are scheduled in the metro Phoenix area.

Boyce Thompson Arboretum – Fall Plant Sale: October 13 (Arboretum members), 14 – 29 (public)

Desert Botanical Garden – Fall Plant Sale: October 19 (Garden members), 20 – 22 (public). Reservations required for entry.

Maricopa County Master Gardener – Fall Festival & Plant Sale: October 21

Center for Native and Urban Wildlife – Fall Plant Sale: October 26 – 28 at Scottsdale Community College.

Borderlands Nursery & Seed – Chandler, AZ Plant Delivery: Order plants in advance via the Borderlands website and pick up at the Chandler Nature Center on November 18 from 10:30-11:30am

Wildflower Seeds

Monsoon season and fall are terrific times to add wildflower seeds to your landscape, assuming it rains! For a wide variety of Arizona native plant seeds, we recommend the following sources:

Maricopa Native Seed Library – This new local project offers native seeds for free! Similar in format to other seed libraries, the public may obtain up to 3 seed packets per month. Available at several Maricopa Community Colleges libraries.

Desert Botanical Garden – Purchase seeds online or in person at their Garden Shop.

Native Seeds/SEARCH – Purchase seeds online from their conservation farm in southern Arizona.

Borderlands Restoration Network – Purchase seeds online or visit their nursery in Patagonia.

If you feel there’s a local nursery, native plant fundraiser, or seed supplier we should add to our list, please let us know!


Participate in a local nature walk or educational event!

Citizen Science Opportunities

These are citizen science and community science projects you can participate in on your own at home, during a walk in your neighborhood, or while visiting Arizona’s public lands.

Document the presence of monarchs and the seasonal changes of milkweed at a location of your choosing, now until June 2023.

Nature’s Notebook

Document the seasonal changes in plants or animals near your home by becoming a USA – National Phenology Network observer.


Observe plants as part of this national program to help scientist understand how plants are responding to long-term changes in climate. Or, join their Milkweeds and Monarchs project which is studying whether monarch butterflies prefer to lay eggs on non-flowering milkweed plants.

Libraries as Hubs for Citizen Science

Visit a participating library that loans out citizen science tools and supplies.

Buffelgrass Green-up

Contribute invasive buffelgrass observations to the USA – National Phenology Network’s Buffelgrass Green-Up phenophase map.

Southwest Monarch Study

Monarchs need milkweed and nectar plants, so hopefully you have these growing in your yard or neighborhood! Join this monarch “tagging” project to help document Western monarch migration.

Desert Defenders

A special initiative in metro Phoenix to identify and map invasive plants. There is also a special project dedicated to locating stinknet (Oncosiphon piluliferum/pilulifer).

Wild Spotter

While visiting National Forests and other wild lands, keep an eye out for invasive plants.

Tamarisk Beetle Monitoring

Help RiversEdge West track the spread of tamarisk beetles (Diorhabda spp.) across the western United States and Mexico. Data is used for an annual distribution map that notes presence and absence of tamarisk beetles.

Western Monarch Milkweed Mapper

If you see milkweed plants or monarch butterflies, eggs, or caterpillars while outdoors, take a photo and submit your sighting to this regional project.

GLOBE Observer

Participate in their Land Cover project to help scientists create better maps. Or, join the Trees project by taking height and circumference measurements.


Native plants attract a variety of birds. Report the type of birds you see in your yard, neighborhood, or local park.

Native flowering plants are essential for bumble bees. Help scientists track their populations by submitting photos of the ones you see.

If you have a rain gauge at home (or decide to purchase one), join this Arizona rainfall monitoring network to submit your daily rainfall totals.


Select from a variety of online projects to contribute to real academic research from your own computer.


Access digitized natural history data online to help transcribe and decipher field notebooks, photographs, museum labels, and data sheets from around the world.

Plant Press Arizona, Summer 2023

Posted on Aug 15, 2023

Plan a Road Trip! Read all about the many Botanical Gardens and Arboreta of Arizona in our online version of Plant Press Arizona.

If you love nature, then Arizona is a great place to live. Its diversity is broad and deep. Where the Colorado River leaves Arizona and flows into Mexico, the elevation is about 70 feet, and the top of Humphrey’s Peak north of Flagstaff is 12,637 above sea level. Annual rainfall in the state ranges from less than 3 inches, near Yuma, to the record 58.92 inches at Hawley Lake in 1978. The topography can be flat or mountainous, and the geology is a very busy scramble.

These contrasts in elevation, precipitation, terrain, and substrate result in a great deal of contrast in ecological zones. That contrast leads to a lot of different plant species — 4,260 according to the Arizona checklist on the website for the Southwest Environmental Information Network (SEINet).

Central Arizona’s Desert Defenders

Posted on Apr 09, 2023

Desert Defenders is a collaborative, community science program focused on finding, mapping, and removing invasive species.

Desert Defenders is a partnership of organizations and volunteers from around the Valley, including the Arizona Native Plant Society. Through individual and collective efforts, native plants and wildlife can thrive!

Learn and help spread word about Desert Defenders by viewing and sharing our new brochure. Also, visit the Maricopa County Parks website to get involved with Desert Defenders volunteer events.
