Mine hasn't rebloomed since I bought it, however it had root problems and I then moved it to S/H. I can see some lovely roots on the new growth which is now almost mature so I'm hoping it may decide to spike soon
I have one of these mounted that I got from a forum member on another forum. It has 3 bulbs with the "third leaf" that indicates it is going to spike, but not yet. I do see some nice new roots forming though. Congrats! I will show this pic to mine to show it what to do next.
