We're trying to grow new plants and use different types of containers to do so.  One thing we're trying is growing potatoes in a recycled bushel container.  I punched holes in the bottom for drainage.  If (keeping my fingers crossed) this works, the vines should look really pretty coming out of the top.  I put a layer of organic container soil (not potting soil, container soil!) in the bottom, placed the seed potatoes on that and then covered with another layer of soil.  We'll see what happens!
