I sowed seed saved from last year, in October and have worried all winter that they have grown a bit too big, but they have mostly survived the frost. 80% are fine and the others look like they will grow again from the base. Are you at altitude or just prone to hard frosts?
As for the variety, I grew two varieties on this plot last year - Bunyards Exhibition and Masterpiece Green Longpod. I then forgot which was which so I'm not sure which seed I planted in the autumn. The other variety was planted this week but the first will take a lot of catching up. If it gets as warm as they forecast I think there will soon be flowers.
