I got some of these from a member at the OCPS forums, they came with baseballish sized tubers and were beginning to produce flowers.
And one of the flowers opened today. Now, I have these on my bedroom windowsill, otherwise I would not be complaining. But waking up to the smell of rotting flesh is rather unpleasant. I actually put them in large clear plastic garbage bags so they won't stink up my room.
Other than the smell (which is somewhere between durian and a rotting corpse) I can't complain, I took them outside for most of the afternoon, and took some photos while they were out there.
These blooms are about 17 inches long:
Thanks for looking!
