The 10 Best Full-Sun Perennials For Your Arizona Garden
Arizona full sun is unforgiving, and the wrong perennials fail fast. Some fade, some collapse, and others never look right once summer settles in, which makes plant choice more important here than almost anywhere else.
The best full-sun perennials for Arizona are built for intense light, dry air, and long stretches of heat. They do not rely on constant water, protection, or pampering to stay attractive.
Instead, they return year after year with steady growth, reliable structure, and consistent color.
When the right plants are in place, full sun stops being a problem and starts working in your favor. Harsh conditions become an advantage, not a fight.
A smart perennial choice creates a garden that looks confident instead of stressed, with less maintenance and better long-term results.
