Update on the Stapelia variegata flower. It matured overnight and now smells like an old trash bag. Very lovely. I put it outside on the balcony with my other overwintering succulents just after I took these pictures.
Quick edit: My glass panels on the balcony are all closed to prevent the succs from getting cold, but it also prevents fresh air from getting in. The heat and sun must have somehow reacted with the flower. Everything out there now smells like a 7 year old rotten room temperature meatloaf. Jesus Christ.
