I bought these Cheiridopsis denticulata (labeled candidissima) in June 2013 and was really worried how they will like my conditions. After all, they are my first Cheiridopsis and winter-growing mesembs are generally a bit tricky on a windowsill. Now I've had them for almost a year and they seem to have completed their yearly life cycle successfully. What a relief! Over the last months, starting as early as November, they've grown new leaves that are simply magnificent. The old ones are wrinkled but I'm allowing them to stay because accordning to my inside sources (Thank you Bob! ;) ) it is okay for them to have several pairs of leaves at a time. In fact one of the plants is pushing another pair (or dare I hope a flower?).
All in all I'm very pleased they are happy with what I can give them in terms of sunlight and substrate and watering schedule. I will reduce waterings during the summer and reprise what I've been doing for the past year.
Not everything is this shiny with Cheiridopsis. Ch. peculiaris didn't make it as well as one of the 5 Ch. denticulata I initially had. Never started any new growth and just withered with time. Acclimation is hard.
