Native Plants for Arizona - What to Plant, and When
Arizona spans 3 ecoregions:North American DesertsTemperate SierrasSouthern Semi-Arid Highlands
180 plants on this site are native to Arizona, 30 of them keystone species that feed the most caterpillars and bees. Arizona spans 3 ecoregions (North American Deserts, Temperate Sierras, Southern Semi-Arid Highlands), and the plants here are the ones that evolved in them. Hardiness zones in the state run 4a to 10b, which is why the list sorts by zone rather than by state.
Start with the keystones (an oak or native cherry if you have room, then goldenrods, asters and milkweeds), and plant in early fall or early spring, at least six weeks before a frost. Pick your zone above and each plant shows its own sowing and bloom window for where you garden.

Common questions
- What plants are native to Arizona?
- Agarita, Alderleaf Mountain Mahogany, Alkali Sacaton, American Vetch, American White Water Lily, Angel's Trumpets, Antelope Bitterbrush, Antelope Horns, and 172 more are native to Arizona. Every one links to its own growing page.
- When should I plant natives in Arizona?
- Timing depends on your hardiness zone. Each plant on this page shows its sowing and bloom window relative to your zone's last spring and first fall frost, so the dates stay correct wherever in Arizona you garden. As a rule, plant perennials and shrubs in early fall, at least six weeks before the first frost, or in spring once the soil drains.
- What hardiness zones does Arizona cover?
- Arizona runs from zone 4a to 10b. Pick your zone at the top of the page and the list re-sorts for it.
- Which keystone plants should I start with in Arizona?
- Arizona Alder, Arroyo Willow, Bigtooth Maple, Black Cherry, Boxelder, Broom Snakeweed, among others. Keystone plants host the most caterpillar species in their ecoregion, which is what feeds nesting birds; one oak or native cherry does more than a bed of showy non-natives. Use the Keystones only toggle to see all 30.
How this list is built
Native ranges follow the USDA PLANTS Database; hardiness ranges follow USDA Plant Hardiness Zones; pollinator value draws on the Xerces Society. Where a reference almanac would stop at “confirm with your local authority,” we go one step further - every plant here links to its full growing page with frost-relative tasks for your zone.
Nature timing varies year to year. To calibrate to your own yard, the Garden Digest builds a weekly task list around your plants and frost dates.
