Tecoma stans v. angustata does grow here but not this far North. I don't think it can withstand the cold. That orange Tacoma vine is an absolute nuisance. Must be giving of suckers and spreads like wildfire suffocating everything else in its wake. In winter it dies down, the roots remain alive but I never seen anything happen to Tacoma stans down to -5c.
