Answer: Wow! I hope your new trees live up to the reputation of the tree you had in PA! The trees that you got were from a florist so I expect that they were grown in a greenhouse and shipped directly from there. Sunshine in a greenhouse isn't the same as Arizona sunshine. And, greenhouses are usually humid - not so in Arizona (except during a monsoon). Your trees, especially the finicky one, will need to be gradually acclimated to the sun. It won't hurt them to sit in bright light on your patio. If the one tree tolerates direct sun, you can leave it in the sun. But the one that balks when it gets direct sun can be left in a bright but not sunny spot. This winter, when the sun's rays are not so intense, you can set it in direct sun. Any new leaves it develops should be able to tolerate next summer's sunshine.
Some of the best plants for attracting hummingbirds are Chuparosa; Arizona Yellow Bell; Baja Fairy Duster; Desert Milkweed; Red Yucca; Turpentine Bush; Desert Willow;
Cascalote; Aloes. Anything with a trumpet shaped flower will also attract them.
Best wishes with your garden!
