Cheshirekat I grew Sweet potatoes here in Tucson several years ago . Had great success. I think potatoes are one of the most fun things to grow.
You never know what surprises are growing under ground, so fun to dig up.
I never really ate sweet potatoes till I grew them and found some good recipes for them.
Check into the daylily forums, lots of nice people. Especially on The Porch Swing.
