Talkback: Cup and saucer vine
I too find sweet peas a great deal of work with all that dead heading and I don't even like cut flowers in the house that much so have started growing Morning Glory instead. Last year I chose a red variety - sorry, name escapes me - and though the flowers were small and short lived they grew in such profusion they gave a great display right through to the frosts. No effort required apart from sowing and planting out. Brilliant.
