~ Editing my original post to say that this plant was identified as
Climbing Hempvine (Mikania scandens)
No blooms yet but I found this sprouting in a bed with a Hibiscus and tied it up to a light post to watch and see if I could figure out what it is. Well, it's been growing for a couple of months now, twining away around the light post but still no blooms. The leaves resemble Ipomoea but not from seed I remember sowing (I've sowed seed of Ipomoea Nil, Ipomoea Crimson Rambler, Ipomoea alba and another one (can't remember the name) but the leaves on this vine are different from all the other MG's. Any guesses??
