Looking for inspiration...

Maybe some Sweet potatoes in large pots or some Yard long beans if you can navigate around the bench?

Tried the Yard Longs once outdoors, plenty of leaves but very few beans. I've tried a lot of different French beans and have eventually found a variety I like which crops early and heavily. Tendergreen is the one for me, readily available cheaply and the only one my neighbours and I really enjoyed this year.  They melt in your mouth!
