Kevin, I've run across them at Lowes from time to time, and even picked up a yellow one there marked down to $5! I made the mistake of keeping my orange one in a room that was too warm last winter. It still bloomed in the spring, but the stalk stayed really short and the blooms were nestled down in the foliage. I received my orange one as a pup from a friend's plant, it bloomed about a year later.
Marie, at least what you have is something really cool and unusual! Do you see Clivia growing in the ground in your area?
