Need, fast growing bush
I need a really fast growing bush or even annual, to shade a very hot Arizona room sliding door. The room gets up above 100 degrees in the summer.
The spot will be in mostly sun, is easily watered, gets a bit of flood irrigation, and needs to be very full/bushy.
Prefer something that would go with my tropical look that I'm trying to work on around my pool.
I was considering yellow bells or their orange relative. Also, perhaps hibiscus or even one of the hardy hibiscus. Maybe swamp mallow? Would any of these grow quickly and work here? Confederate rose?
It will get some shade in the afternoon from the large pine trees and house, especially when smaller.
