Is it possible to sow sweetpea seeds directly in to a large patio container now and leave them to germinate and hopefully see them flower next summer without any lifting or potting on. Appreciate your thoughts?

This is possible, and really the better way to do it. They don't particularly like transplanting, so if they can be planted in their terminal pot, then they will appreciate this. Just make sure to plant them 6 inches to a foot apart.
