Ugly Plant

We have the ugliest plant growing right next to the front door of our house. It looks like a huge swamp weed and it grows like crazy. Last year I cut it down to the ground a few times and tried to dig it out once. I hadn't gotten around to cutting it out this year although every time I looked at it - it drove me crazy. Yesterday I went outside and this is what I found:The most beautiful pink calla lilies I have ever seen are growing out of that horrible plant. I guess you really shouldn't judge a book by it's cover - or a plant by it's leaves...
