This is all from 4 seeds. I've really enjoyed this climber. ( photo / image / picture from Donna S's Garden )
Oh you must be in zone 7 a and b. It only likes it in 10. The whole plant will be dead outside even in your Winter. I'd be digging it up and letting it live in my greenhouse if we lived closer. LOL.
I hope the frosts stay away for you for a good while yet. Your plant is really lovely with those intense blue flowers it would be a shame if it was killed off by the cold weather.
