Answer: The USDA hardiness zones are simply based on the average minimum winter temperature. I have a map here that shows SW Scotland as zone 8, with a minimum winter temperature of 10 to 20F. As you can see, that designation isn't all that useful to you in determining what plants will do well--in the U.S., zone 8 includes much of eastern Texas, east to Georgia, and even includes parts of Arizona. Of course, you wouldn't have any problem ripening tomatoes in these areas! The zone designation will simply tell you what perennial plants should overwinter successfully.<br><br>Can you visit with some neighbors, and find out what varieties they grow? They would be the best people to give you some insight. One tomato variety you might try comes to mind--'San Francisco', available from Bountiful Gardens. Their e-mail address is firstname.lastname@example.org<br><br>Good Luck!
