No i.d. for this plant
I have had this plant a few years and not seen this before. There are two recently matured pbulbs that have what looks like a much smaller pbulb growing on top, and one of those has pushed out a weak looking spike! (doesn't look like the buds are likely to develop to me).
I don't generally use superthrive, so that's not the cause ...
Is this something that just happens sometimes?
We'll see if that spike actually blooms
I just found it very interesting
