You could try a number of penstemon species such as penstemon eatonii, penstemon barbatus coccineus, or penstemon pinifolious. All of which are great drought tolerant/heat resistant hummer plants. Although in Phoenix i would give them part shade since it gets so hot. Another possibility could be red-hot poker which is relatively drought tolereant as well. Im sure aloe sp. would also thrive in Phoenix, i had a huge aloe plant in my front yard when i lived in california(Zone 9 as well) and it drew in the hummingbirds when it was in bloom.

Hummers love honeysuckle.

I would say yuccas, Aloe, Mexican flame honeysuckle, coral bean, Baja fairy duster, century plant, and hummingbird mint.

My favorites for hummingbirds are salvia guaranitica and lonicera sempervirens (coral honeysuckle). I don't know what does best in your zone because I'm in Missouri. I will link you to a red honeysuckle called Major Wheeler in High Country Gardens' catalog but you will want to look through their whole catalog. They have LOTS of hummingbird plants that will do well in your area.
