Beetroot - the leaves are beautiful.
When I lived in the inner city with only a front garden, I grew broad beans amongst the flowers - passers by stopped and asked what the beautiful black and white flowers were.
Chives - the ordinary and Chinese chives - both have lovely allium-type flowers ('cos they are alliums )
Courgettes look good if you have the space - get the bush not the trailing type - and then you have fantastic structural large-leaved plants with beautiful golden flowers.
