I left my Christmas cactus outside all summer and all fall. (I live in the south.) I brought it inside on Thanksgiving and it began to bloom.
What nicer gardening decor than a blooming cactus. They make you come alive when they decide to bloom. I am lucky with the two large plants I have, because they bloom each season.
Thor Olga is one of the first Christmas cactus (Schlumbergera) that I obtained. It always is so attractive with its red and white colors against the green of the foliage of the plant itself.
This is supposed to be a Christmas cactus, but it has bloomed only in the last week. My husband said it must be an Easter cactus. This is the first time it has had so many blooms at once.
In our mild and rather warmish climate near the coastal plain of S. California, our Christmas cactus often bloom in the summer. Here is one from August, 2016.
A friend once called this bloom, 'Angel Wings.' The blooms will soon be opening in large numbers. Photographed with a digital camera in the morning under the patio cover.
The Christmas Cactus (Schlumbergera) are not real Cactus plants. They are in the succulent family. These two are currently blooming on my North facing patio in partial shade.
I have grown Christmas Cactus (Schlumbergera) for many years. Living in a mild and temperate climate, I get blooms a few times a year, and the colors are magnificent.
My Christmas cactus bloomed just in time for the holiday this morning. You can see another blossom ready to open, maybe I'll see it on Christmas morning.
