fast growing vines for patio
I installed several planter boxes with attached trellises as "walls" on my patio. I planted kiwi and grape several months ago, with the goal of them growing up the trellis and then further onto the roof structure, to provide shade (and fruits).
The plants look a bit sad, I don't know if they survived the winter or not. I hope they did and will start growing soon. But just to hedge my bets, I'd like to stick in some other vines that grow real fast, so that I can have a covered patio as quickly as possible. If/when the grapes and kiwi grow, I will cut the other stuff back. I'm looking for suggestions for fast-growing vines that would grow well in planter boxes. The patio gets plenty of sun.
