I've been growing this for three years, and it has been a favorite of mine ever since. Tough as heck and extremely adaptable.
Now, it sent out four spikes!
Two spikes begin to emerge from sheaths (one from dried up old sheath! Surprise!), and I can see two more developing inside the sheaths on the other pseudobulbs.
Even the stunted bulb at the middle (which was nearly squeeze to death by entangled root, so I had to cut away the root mass to rescue it) is developing some sort of sheath It is getting better and better every year....I am totally in love with this one!
