Best plants for Arizona
These species reliably perform in Arizona's climate — a blend of regionally-adapted ornamentals and native plants that don't need babying once established. Start with this short list, then expand once you know your specific microclimate (slope, shade, drainage).
- Desert willow
- Lavender
- Pomegranate
- Rosemary
- Saguaro cactus
- Bougainvillea
- Citrus
- Mexican fence post cactus
- Texas sage
Native plants of Arizona
Natives evolved alongside Arizona's soils, pollinators, and weather patterns, so they need almost no supplemental water or fertilizer once established. Mixing 30-50% natives into a garden dramatically improves its drought resilience and its value to local birds and pollinators.
- Saguaro (Carnegiea gigantea)
- Palo verde (Parkinsonia florida)
- Ocotillo
- Desert marigold
- Arizona poppy

Frost dates and timing in Arizona
Average last spring frost: late January (Phoenix) to late May (Flagstaff). Average first fall frost: early October (high country) to mid-December (low desert). Growing season runs about 120-330 days. As always, average dates are starting points — set seedlings out a week or two later than the average last-frost for high-value crops like tomatoes and peppers, and have row cover or frost blankets ready for an unseasonable late freeze.
Use the fall planting schedule by zone to plan your second crop, and the vegetable garden planting schedule for week-by-week spring timing.
Soils and amendment in Arizona
Alkaline, low-organic-matter desert soils in the south; volcanic and sandy loams in the northern high country.
Challenges specific to Arizona
Intense summer heat (110°F+), monsoon downpours, alkaline caliche soils, and javelina/rabbit pressure on tender new plantings.
For drought-prone parts of Arizona, see the drought-tolerant garden design guide. If your yard sits low and stays wet, the drainage fix without regrading guide covers raised beds, French drains, and bog-tolerant planting palettes.

›What USDA hardiness zones is Arizona in?
Arizona spans USDA zones 4b-10b. Phoenix and the low desert hit zone 10b while Flagstaff and the high country drop to zone 4b — a 6,000+ foot elevation span produces wildly different plant lists. Match plant cold-hardiness ratings to your local zone — pushing into warmer-rated species is a gamble against the next hard winter.
›When is the last spring frost in Arizona?
Average last spring frost in Arizona is around late January (Phoenix) to late May (Flagstaff), and the first fall frost typically arrives early October (high country) to mid-December (low desert). That gives a typical growing season of 120-330 days. Average dates are starting points — set seedlings out a week or two later than the average for safety.
