Heather, not sure what references you've consulted, but Hillerman (Mr. Angraecum) has this one listed as W-I, so I've never let mine get very cold...it doesn't seem to need any special treatment to bloom and does so on and off year-round.
Thanks Robin, I was hoping you might weigh in.
I'm just considering maybe getting one some day. I'm looking for things that can take average temperatures of 55-70 cause I am growing in the basement now and am finding my temps are in the cooler range, generally.
It might do alright for you if the rest of its preferences are met, namely great water, flushing and lots of air movement. Brenda would know better than I whether it's worth the gamble for you. She might also know where you can find an Angraecum rutenbergianum--that's one that for sure likes it cool. I resisted the urge to buy one and kill it when I had the chance; no clue if Malala Orchids has a new U.S. contact since Bert Pressman's passing, though I'd like to know.
