I visited the shop were I bought it not long ago and found that the species obviously hadn’t attracted the attention of mny other buyers, since there was almost as many left as when I first visited.
The remaining plants were situated in a ‘bookshelf’ with a lot of other items and was a couple of meters away from the window. In other words, they didn’t got that much light or any sun exposure I would guess. All these plants ( about ten) had leaves but no flowers.
This got me wondering why and after going trough quite a few pages with care advice I am not that much wiser..

Searching for habitat pics I didn’t found enough to give me a clear understanding of what’s the ‘normal’ look of this plant in habitat.
My theory which may be way off, is that the probably a bit light starved plants in the shop tried to get as much light as possible by producing leaves? Or is it my care that is lacking, so my plant doesn’t really thrive? Maybe I am watering too little in the growing season?
