I am not sure whether this is a meristem or a selfing - it was not said to be that, so probably the former. Flowers a bit small, and not many of them , but this is the first flowering of this plant. A little bit unusual, I think.
Btw, I snapped it on a pocket camera, when I popped into the greenhouse earlier and found the sun shining through the flower - an effect I would not have thought of for myself.
