Christmas Cactus (Schlumbergera truncata)
Species: Schlumbergera truncata.
Though I use the popular name 'Christmas Cactus' it should rightly be called 'Thanksgiving Cactus' (Schlumbergera truncata) as it normally flowers during November.
The true Christmas Cactus is Schlumbergera x buckleyi. It is seldom found in the shops or garden centres as it starts to flower too late for commercial growers.
