We acquired a few very large flower pots with the idea of putting them on our flat rooftop to soften the appearance of the house. Unfortunately, the plants we chose don't hold up to the breeze very well and their leaves are getting shredded in the wind. It can get pretty breezy here at 530 meters. Anyone know a an appropriate plant that can endure windy conditions better but will still work as a potted (though very large pot) plant?
