We have a southwest facing corner balcony that gets a lot of sun. I'd really like to plant a vine or two along the metal edge of the balcony. (Not sure what the proper term is?) For the last couple years I've been trying to grow a vegetable garden on the balcony, since I'm used to veggie gardens. It never worked--in particular, we always seemed to go traveling just when the cherry tomatoes and zucchini got going (and it was really all about tomatoes and zucchini). Also watering every day didn't seem to be enough during part of the summer--this may still be something I need to work out. Recently I realized that what would really be best would be a soothing, mostly green garden with some flowers and edibles. The most important part of this would be vines. The absolute ideal would be evergreen vines--you know how nice it can be to look outside and see some green in the wintertime. (Or even just for the mild parts of winter.) Although maybe there could be just one evergreen and a couple of non-evergreens. So far I've had two ideas: clematis (armandii or cirrhosa?), and a rambling rose (adelaide d'orleans?). Do you have any ideas? Anything else I should know about? Thank you!
