Here in the desert southwest, a variety of wild sunflower grows in many locations. I've seen these from Arizona to our desert near Palm Springs. These are not the mammoth sunflowers like you find in gardens. Oh, no! These are a wild variety that seems to be able to grow without much water. I cultivated some seeds from around the valley and planted them in my yard last spring. They are still blooming long after my mammoth ones dried out and died. The only thing I noticed was that they were difficult to get started. Perhaps they need massive amounts of water to get started? I would love to collect more seeds again and see if this year I can do a better job with them. And, yes, they grow in places that do not receive any water as I see a whole stand of them by my school out in a field that doesn't get any additional watering.
