Over 10 decades ago I got a Christmas cactus in December that bloomed every year a week or two before Christmas. Then in 2008 it all of sudden bloomed for my Leap Year in February!! After that it seemed to bloom for all and any holidays from Christmas to Halloween, Mother's Day, Father's Day, Thanksgiving and, yes, in February!!
For a year or two it only bloomed once or twice a year and then in 2016 it once again bloomed two weeks before February 29th!
Since then there doesn't seem to be any rhyme or reason but it blooms at least 6 months out of the year. Last week when I was watering the plants and got to the 'Christmas' cactus I noticed buds and now there is a bloom with many more to come as there are buds all over the plant!
