Arizona is a land of contradictions.
Whilst the images that come to people’s minds when they think of the state are often barren expanses of low-lying deserts, saguaro cactus, and hardy shrub life, according to Britannica more than half of the state lies at least 4 000 ft above sea level.
This variety in landscape means the state offers a wide range of evergreen species for you to grow.
