Any fruit or veg that like boggy areas?

Albertopia is half way up a slope which means that whilst the top drains and stands the risk of being very dry in the summer the bottom resembles a paddy field. Apart from growing rice there is there anything that would tolerate slightly boggy ground? If not then I'll extend the standing area and have pots on it

Raised beds would help a bit. Our soil is workable despite the ongoing deluge, and I am convinced that raised beds have contributed to this, along with large amounts of organic matter

and I'll add celeriac to the boggy plant list 

Brilliant thanks it's only a half plot so would like to use as much as possible. You never know come autumn I might have enough success for a small side salad 

Oooooo cranberries  . Haven't tested the soil for acidity though....bad huh?

Quince too....this might end up being my most productive part of the plot!
