Unearthed a THING in my backyard
Last year, there was this large plant with black berries on it growing in my backyard. It was uninvited, so when I saw a spout coming up in the same spot this year, I tried to pull it out. It wouldn't come out, so I got a shovel and started digging.
A half hour later, I had unearthed a huge...THING... weighed several pounds, it looks like a twisty potato that's a foot and a half long and four inches thick! I'm assuming it's a corm or something. Does anyone know what kind of plant this is?
The plant had red stems, maybe 4 feet high, and there were 4-inch cylinder-shaped black berry clusters at the end of each branch.
