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 local native plant sales are scheduled.

Pop-up Plant Sale at SRP Water Conservation Expo: (Tempe, AZ)  March 4. Advance event registration required.

Boyce Thompson Arboretum – Spring Plant Sale: (Superior, AZ)  March 10 (Arboretum members), March 11-27 (public).

Desert Botanical Garden – Spring Plant Sale: (Phoenix, AZ)  March 16 (members), March 17 – 19 (public). Reservation required for entry.

Maricopa County Master Gardener – Spring Plant Sale: (Phoenix, AZ)  March 18. Reservation required for entry.

Butterfly Wonderland – Spring Plant Sale: (Scottsdale, AZ)  March 18-19.

Center for Native and Urban Wildlife (CNUW) – Spring Plant Sale: (Scottsdale, AZ)  March 23-25. CNUW is also accepting donations of used pots (especially 1 gallon size), which they will happily reuse in their greenhouse.

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!


Additional Chapter Announcements

Invasive Species Alert: Stinknet

Help control the spread of Stinknet to protect native habitats and prevent wildfires!

Also known as Globe chamomile (Oncosiphon pilluliferum), Stinknet is a noxious weed that is spreading quickly throughout central Arizona. In Spring and early Summer, flowering Stinknet plants can easily be spotted, as they look like little yellow lollipops. If you have it on your property, take action to remove and dispose of the plants before the seeds ripen and have a chance to spread!

Learn more by viewing our Stinknet pamphlet, which is available in English and Spanish. Please download, read, and share this important information with others!

Plant Profile: Flattop Buckwheat

Posted on Jun 20, 2022

Who Put the ‘B’ in Buckwheat?

By Kathleen M. McCoy, AZNPS Phoenix Chapter Member

Leer en español

Does “flattop buckwheat” summon visions of stacks of pancakes dripping in delicious honey? If so, your mouthwatering vision is partially correct. Flattop buckwheat (Eriogonum fasciculatum var. polifolium), also known as Eastern Mojave buckwheat, is a low, rounded, fast-growing shrub not to be confused with common buckwheat (Fagopyrum esculentum), a domestic crop cultivated for edible seeds.

Across the entire Southwest over 355 members of the buckwheat family (Polygonaceae), often difficult to distinguish structurally, find their home in sunny coarse and well drained soils along washes and rocky slopes. In the Mojave and Sonoran Deserts, E. fasciculatum is the most common buckwheat.

Although lots of Flattop buckwheat decorate the desert, this miniature evergreen fully grown is usually only 1 foot tall by 2 feet wide with typical desert gray-green foliage. Arriving in late spring, clusters of flat-topped white flowers gradually turn pink in summer, then rust colored in fall.

The ‘B’ in buckwheat is for butterflies, bees, and birds. The slightly fragrant flowers are a wildly popular lure for several butterflies, most notably the Mormon metalmark (Apodemia mormo), the Rocky Mountain dotted-blue (Euphilotes ancilla) and the Lupine blue (Icaricia lupini). These butterflies also use Flattop buckwheat as a host plant for their caterpillars.

A favorite of bees, native and nonnative, this pollinator plant provides a good source of nectar. Luckily for humans, bees use these plants predominantly as a basis for tasty honey. Not only is this honey healthy for our diets, but also for the economy. E. fasciculatum is the principal honey-producing plant in southern California. When other flowers have long gone to seed, flattop buckwheat still supplies food for hungry birds due to its extensive growing season.

In fact, some farmers use buckwheat for a dual purpose, making honey and as a form of integrated pest management. When planted next to crops or in cultivated gardens, their nectar attracts beneficial insects that in turn reduce pests. Pest reduction means less need for chemicals in our flower beds and vegetables. Flattop buckwheat can also serve as a ground cover crop, helping to improve soil health plus providing crops protection from soilborne pathogens.

Wild E. fasciculatum is a low-profile desert plant, often overlooked and underappreciated. If you want to enhance and create an almost year-round pollinator garden, raise Flattop buckwheat… a low maintenance, easy-to-grow plant that sweetens the pot for butterflies, bees, birds, and possibly your buckwheat pancakes.

Arizona’s Desert Tortoise Adoption Program

Posted on May 23, 2022

Did you know that Arizona has a Desert Tortoise adoption program?

This was the topic of the Phoenix Chapter’s May meeting. Kellie Tharpe of the Arizona Game and Fish Department gave a feature presentation. The recording is available to watch any time on the AZNPS YouTube Channel.

Watch the video to learn about the adoption program, including how to create tortoise habitat in your yard using native plants!

Information about the adoption program is available on the Arizona Game and Fish Department website. Also, for a list of native plants that tortoises love to eat, see the Native Plants for Desert Tortoises pamphlet.
