ZGETMAN 6B is the warmer part of zone 6. Gardening zones count the most when you are looking at perrenial plants because their main consideration is how cold it gets. Since in vegetable gardening most plants are annuals, a big facter is last and first freeze dates. You can check with your local county extention office or Master Gardeners to find out that information. There are a few perrenial vegetables, asparagus, rhubarb and artichokes are the main ones that come to mind. You would be fine with asparagus and rhubarb and might do ok with artichokes in a protected area.
I actually think you can go up a zone instead of down. I'm technically zone 5a but have had luck all the way up to zone 7 perennials depending on where I plant them. It's kind of trial and error. I've had zone 5 fail because I planted them in containers and didn't give them enough protection during a winter with a lot of freezes and thaws, freezes and thaws.
Welcome to the team - I'm in 5/6 and I would never have thought that anywhere in Texas would be as cold as zone 5/6. I'm on the Canadian border. Are you sure that's what you are? I would have thought you would be more a zone 7 down there. I read your intro post about watering a lot - mulching helps plants from drying out and drip irrigation uses much less than watering overhead.

In the "introduce yourself to the team" forum there is a thread asking what zone people are in. It isn't a sticky topic, so if people don't post on it, it moves back along the list. A few people responded there, but not many. I'm in zone 5 in the Midwest - near Chicago.
