Yep thats why I'm hesitant on it, I don't want to wind up neighbors yards or invade anywhere. it never grew back back home and it does get colder here in the winter, I really don't know if it makes a difference or not though, I'm only 1 zone down from back home.
Oh man you should see the ivy here too! Everywhere I move I fight ivy it seems like. it took two years to somewhat get it under control at our previous house. Now I see it spreading in the shady area of the far part of our yard. Yay!
Morning Glories are so beautiful though, I really like them but I think it might be for the best that I accidently killed mine lol.
I can't wait to see how the honeysuckle does over the next few years.
