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

[arugula]

Edible flowers? Nasturtiums or something a bit different?

[allotmentann]

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

[sarajane]

some thyme plantsmaybe, very pretty spilling over the sides ?

[stompy]

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

yes i love nastusium leaves in salads and with egg sarnies. Just discovered a semi-trailing, yellow striped marrow with a red nastursium could look good.
