Hi. I'm looking for a vine that could grow over the play fort in our backyard. It is a 4-sided wooden structure that is open on top. I'll cover it with lattice for the vines to climb along. The area is shady in the morning but gets mostly sun in the afternoon.

I considered wisteria, but would prefer a plant that is not poisonous, since kids will be playing under it. Grapevine might be fun, but is it fast-growing? I'd like to have the fort covered before the kids are too old to play in it. ;)

Thanks for your ideas!
