we had trumpet vine in our last home northwest of houston, tx i'm guessing it was "wild" but i'm not sure
the house was 35 years old, had an established lawn but had trumpet vine "volunteering" everywhere... the more you pulled up or "poisoned" the more came behind it (even with a paintbrush and brushkiller) every flower bed, rose bush, tree, had it growing up it
i will never plant a vining plant never never never
we also had 6 ft tall four oclocks everywhere
i was soooooooo glad to move.....12 years of those battles were enough..
