i think it may need a bit of a cool down during the winter time but i could be wrong. think it can tolerate lower temps than most phals.
My place is currently cool (at about 14-18C) and I reduce water to once a week, my plant seems fine. Actually I only have it for 2 months, and I notice that it already anchored well after repotting since I have it. I am looking forward to its flowers the next spring.
