It bloomed...altough IOSPE says it usually has 6 flowers, this has only two, probably because I am giving it too much light (full sun for several hours straight, since middle of the morning until late afternoon).
It is a vigorous but slow growing plant...
As to the flower count, if this is the first blooming then that could be another reason why there are only 2 flowers.
Well, this is a small size plant and I really don't know if this is a young plant or not. This is the first bloom under my care and I haven't seen any older sheaths when I bought it so its age might be a reason.
