Potatoes growing out of a bag of soil in my kitchen. About half a dozen organic potatoes sprouted before I could eat them, and this is the result.
Now I wait for the plants to bloom, then die, then I dig up the 'taters!
Another photo where you can see the grow bag. (Parsley is growing out of the coffee can) More photos of plants growing out of bags of soil can be found here: http://www.flickr.com/groups/1112006@N23/
