My MIL received this plant as a comp from burgess for being out of stock on the item she wanted. She has no idea what it is. She's had it a few years now and every winter it seems to die completely and new stalks sprout each year right around the old ones. As you can see its already about 25' tall w/ huge leaves. The closest picture I've seen to anything like it are a couple Princess Or Empress trees. But this particular one has never flowered and doesn't produce any seeds or anything other than the leaves.
