I have my plumeria happily wintering over in a sunny greenhouse that I can keep an average of 78 in the day and 55 at night. It's been a freaky mild winter so far. I could sense they almost didn't want to go dormant. I have one Orange NOID purchased locally that usually doesn't go dormant that remains leafy and green.There is one 10" cutting of Riviera Rainbow that refuses to go dormant. But she has mites, I think? sigh The challenge never ends no matter what the season.
