I got this cactus at a plant swap a couple of years ago. It's Stapelia gigantea, or Corpse (Carrion) Flower Cactus. I spent the first year or so dividing it and giving it as gifts or taking it to plant swaps. We had a really cold winter this year and the cactus seemed a bit traumatized by the weather. It just got some new growth recently - really the first sign on life it's shown since last year.
So when I saw a bud forming, I was excited, as well as surprised. It took about two and a half weeks from the time I noticed it until it bloomed today. I've been watching it intently the last couple of days - it's looked like it was was going to burst any minute. I went to take a photo this afternoon, before it opened, and that's when I noticed it had opened. We all had to go look at it, and take pictures, AND SMELL IT!
We really didn't smell anything, so I put my nose right up in it. That's when I got the faint smell of roadkill. I'm just happy my plant bloomed and it didn't smell as bad as I anticipated.
