Suggestion for long vine over trellis
I'm looking for a hardy vine -- about 15 feet long--to climb my arched trellis. I haven't had much success with Clematis, which, for me, only seems to grow to about 5 feet.
Can someone suggest a long, vigorous vine for a sunny location in zone 5? Flowers would be great, but not a deal breaker. I was thinking of boston or english ivy, but I've read some negative reports about ivy on this forum.
