Oh dear, that is not good at all. Right now we are having a pretty severe heatwave. No rust here, just desert weather. My tillandsias were soaked all night long so that they do not dry out, found only one flowering. Would hate to lose them. Such tiny things and so pricey. At least my begonias at work are doing fine. Had flowers already or I would post a photo to show the large leaves. They like the air conditioning though.
