I have three Christmas cactus plants that I grow on a table by my dining room window. They begin forming buds now in early December for the Christmas time bloom.
They rarely make it all the way to Christmas. As a matter of fact, these, or at least the white one, will probably open up this week. The pink seems to open up a little later.
I know that this blooming is triggered by the amount of daylight (or lack of) that they receive in the fall, but it still seems sort of magical. Like they are dressing in their season’s best for the holiday.
