That cucumber vine is new here in the past few years. It has been climbing tall trees and it is beautiful but then it dies (or goes dormant?) and it looks brown and awful for months. We have been pulling it out which is easy except for having to crawl under shrubs to grab the roots, which go underground for a long way. We couldn't find the ends- they easily break off. Is this on an invasive list? I don't know the botanical name to find it. Min3
