Noticed this growth on my one year old keiki when it was just a bump. I didn't know if it was going to be a keiki or a bloom, but I guess, no question, it's going to be a keiki. I would be very surprised that a young keiki could make a new keiki.
They had leaves on them until mid winter when they turned yellow and fell off one at a time. I removed the keikis from the mother plant and potted them up last August. They had 4 leaves each then.
