Dear George -- I'm in Zone 7 so I don't know if this is transferable to you down there in the deep south, but I've had terrific production from the Navaho thornless blackberry. They produced the very first year (they are 3 years old now) and each year the berries have been getting bigger. This summer they were as big as the last joint in my thumb! Huge. Made blackberry vinegar as Christmas gifts last year. I'm really pleased with them and recommend this type.
