wishing well ideas please

I've been given a small, past its best, wishing well for the lotty any ideas for use preferably pretty and edible?

How about Welsh/everlasting onions? Edible with pretty flowers?

Definately nasturtiums as they will draw the bees in from miles around and will also draw the cabage whites away from, your cabages 
You caould also plant sweet peas too as they will clinb all over the top and the nasturtiums will grow around the bottom
