Just over a year ago, one of my nursery children bought me a cactus as a goodbye present. It flowered till Christmas, and I thought it was probably what we used to call a Christmas cactus. But then it flowered again all through the Spring. When it paused in the summer and began to look a bit sorry for itself, I gave it some fertilizer and hey presto, here it is flowering like mad again! I don't think I've ever had such a successful house plant......except for an African violet I had years ago, which flowered riotously until I noticed it, and promptly watered it to death!
I shall studiously continue to treat this lovely cactus with haphazard care and attention, and hope it continues for a few more seasons in glory!
