I confess I have only just learned Christmas cactus belong to the genus Schlumbergera, but this is a plant I have known all my life.
Ubiquitous in the home of every relative and friend I knew as a child, a Christmas cactus was one of those plants easily shared and easily tended and thus passed-along and treasured as an heirloom.
This one, full of timely blooms, is commanding attention. It was a gift several years ago from former neighbors, who across the miles continue to be special friends. Being able to associate my plants with people is one of the pleasures of gardening.
