Whilst large swathes of Arizona are taken up by three deserts, this doesn’t mean that gardeners will have to settle for skimpy returns on their efforts.

About half of Arizona is semi-arid, one-third is arid and the rest is humid.

The Basin and Range areas have a semi-arid and arid subtropical climate that attracts many winter visitors. Whilst light frosts may occur here, the climate gives gardeners many options to experiment with.

Whether you’re in the Colorado Plateau or Flagstaff, where temperatures are often 30 °F (17 °C) cooler than those of Phoenix, there are plenty of flowering trees for you to choose from.

Arizona In Bloom

The vast state of Arizona stretches from zones 4b in the Colorado Plateau, or Central Highlands, to 10b in the warmer areas of the Basin and Range. Consequently, there are plenty of flowering trees for you to choose from to plant in your garden.

If you’re in the desert lowlands, just remember that some trees may have to be provided with a micro-climate that incorporates afternoon shade from the harsh southern sun and have some drought tolerance to survive.

Take a look at our planting zone guide for Arizona to find out where you are located in it and which flowering trees are best suited to your area.
