It's such a wonderful plant. It grows leaves all the time keeping me at ease (I always get worried when there hasn't been any growth for a while). I really love the texture of its juicy leaves, so velvety soft to the touch. Underground it has nice thick roots which I hope to display one day. It might take several years though. The plant was trying to flower last year but didn't make it (a problem I also had with lithops). Maybe this year?
About the flowers, I've started using valerian flower extract lately that should support flower buds (among other things). It does smell but not more than the medical valerian extract (with alcohol) so it's safe for indoors if you keep the bottle open just as long as needed. We'll see if it's good when the flowering season comes.
