please help identify mysterious plant
I was hoping that someone would recognize this strange plant that started growing in our garden. It seems to be a perennial as it is the second year in a row we've seen it, but last year it died before it got to this point. I think it's some sort of flower....strange mutated calla lily like thing. It seems to be attracting a lot of flies. It only opened up this morning. My husband is the gardener in the family and he doesn't recall planting anything like this.
