I forgot to take pics
I'll try to remember next year and document the process.
I think mustang grapes are somewhat simular to muscadines. I believe muscadines would grow well in your area because they are "native" all the way west to Texas. They are very heat tolerant. They grow wild everywhere around here but a pain to gather. They usually grow to the tops of trees and are impossile to reach. I planted some on horizonal trelisses.
The cultivated varieties are reasonablly cheap. I bought mine from here: http://isons.com/index.html
I found a wild scuppernog vine in the edge of a field and last spring I laid a runner along the ground and placed a rock on it. Around February I will cut it and plant it also in my "vineyard".
