That's correct. One common name for this species of trillium is "Bloody Butcher." I rather like the connotation of this sensuously vulvular looking flower taking on the dichotomously opposing pathological persona of a slaughtering maniac. It seems poetically aligned
with the Black Widow phenomenon.
By another name,
most would call this spring ephemeral
Trillium recurvatum or "Red Trillium."
This particular patch of trillium recurvatum is currently blooming at Prince's Point State Wildlife Area in Jefferson County. I have been watching this and some others in Dane County for a couple weeks and was delighted to find these perfectly in bloom.
On a chilly day, this flower is mother-fucking HOT!
