wow. what a flower
i had an acacallis cyanea for a little while that a former orchid club president gave me, but eventually I dried it out once too many times. I have a culture sheet that points out that it's always in the low to mid 80's during the day, and never lower than 70 at night. always high humidity, very bright, and the lowest rainfall month is around 1.5 inches, and the high rainfall month is over 10 inches!
it also says that it dislikes staleness around the roots.... that's a tough nut to crack! probably if you put it in a bright hot spot and then have some water continually dripping over a mount or through a semi-hydro pot, might do it. lots of leaching looks important, too
