By way of contrast my Christmas Cacti are in flower, they never cease to amaze me. In 2014 they were all pretty much neglected standing on a rack in the porch and only getting water spasmodically yet they flowered in October with a few flowers still emerging in the spring. Last year (2015) I put them outside, mainly because they were taking up too much space, and they appeared to thrive, the regular watering (rain) certainly cheered them up no end. They were brought in as frost was imminent, left in the porch for a while and brought in to the house when they started to show bud but have only just decided to come into flower.
Epiphyllums, they are now known as Schlumbergeras. Through breeding the colour range has extended considerably and there are meant to be two main strains of cultivars, one based on the original Schlumbergera truncata (syn. Zygocactus truncatus) and the other derived from Schlumbergera russelliana known as the Buckleyi Group. The problem lies in that my plants show characteristics of both strains on each plant, in fact the only difference I can detect is that two of them have stems more in line with the Buckleyi Group, these are more rounded and are woodier to the point of being brittle, so all well and good you would think but the flowers belong to the description of those of the Truncata Group. Confused ..................... I certainly am.
