Sorry I did not see the notifications for this!
It was blooming size when I got it, and so was the other twinkle I have. I never notice the spikes growing because I now leave the plant in a place I tend to forget about D: Whenever I remember it and take it out, it usually has spikes all over it!
Smaller orchids do tend to grow more slowly, though. Good luck! I've noticed that this plant really likes warmer temps, if that helps...
lotis146- Thank you! It has lost a few leaves from a short bout of bacterial infection, but it has at least 8 spikes on it right now
