I have always loved these cacti and they were always a part of our lives. i had a true xmas cactus that was a start from my mother's plant for 34 yrs. I became ill and wasn't paying much attention to my plants and even had to find a home for my parrot. the plant turned yellow and died. I have since found two true xmas cacti. one with narrower very dark green "leaves and one with broader leaves and a lighter green.
both exhibit the same red/magenta perfect hose-in hose flowers. True X-mas cacti are really hand me down plants and I have never seen them offered for sale by nursuries. One can normally only locate the Thanksgiving and Easter types. For a source try E-bay or look for plants being summered on shady old fashioned front porches and ask politely for a cutting. Gardeners love to share God's beauty.
