Red trumpet vine - Campsis radicans
We have just returned from holiday with some seeds of the red trumpet vine (Campsis radicans). I understand the seeds need a period of cold (stratification) to germinate. I wonder if anyone else successfully grows this plant in Zone 11. I am a bit worried it may be very rampant but produce few flowers. I have seen this beautiful plant in several states of USA, but all had much colder winters than here. - Ian.
