I live on the edge of the mountains in a very shady area and am looking for something that would bear fruit and grow on a trellis. The reason being is I am trying to devise a way to harvest rainwater off of a building in my yard into a cistern that is 30 feet away. The trellis and vine, I was thinking would provide support for the guttering and hide a little bit of the unsightlyness. What I don't know is what would grow well in a shady and a little cooler environment. The first thing we thought about was grapes, which would turn into jelly for the kids, but I don't know if they thrive in this environment. If anyone has any suggestions or experience to provide me it would be greatly appreciated. Thanks.
