This is the second spike that my Psychopsis has sent out, with a third on the way. Initially it looked normal, but after the first bud was about 1/3 of the way formed, it started forming another on the same spike! I didn't think it would continue to grow but it has, and I'm curious as to what it's going to do! I'll post again once it's bloomed.
I think you just got really lucky. I saw a pic of one recently on another site that was carrying two flowers on one spike at the same time. I think yours is gonna do the same!
