Thanks Kristi
@pod. I'd actually found that A&M site and read it. The one in Granbury had grown well beyond what a deer could reach. It was growing on an arch probably 12-15' high or more in downtown Granbury. Couldn't see what construction material of the arch driving by because the vine completely covered it and in turn was completely covered in blooms. It looked like something you'd see in the Rose Bowl parade. That's how thick the blooms were.
I couldn't tell from the A&M page how hard the suckers would be to control. The seeds sound easy to germinate, but I don't know how quickly they would make a blooming vine.
Nothing like hearing first hand experience to find out the drawbacks and hard they are to manage.
