There's a really fun one in Hopland, CA at the Real Goods site. If you go to see it you might try and time your visit for the upcoming festival. They have a gazebo/pavillion with seating and a raised back portion which is a planter. There are olive trees back there. Then there is a bowl shaped trellis over the entire pavillion with lush hop vines growing to the top. It's amazing how much cooler it is under there. Grape vines do work nicely too. Also Kiwi vines. In Williamsburg, VA, one of the restaurants has an outdoor eating area with an arbor over it. They have 3 different plants growing over it I think but I can't remember what they are. You can also grow trees and graft their branches together to make a fence or an arbor. Sharon gordonse@one.net
