Thanks for the replies
I was pretty sure it's a bud, but didn't want to get my hopes up too high without knowing for sure!!
20jlr, I'm not sure how big this orchid gets. But it hasn't really gotten any bigger in the three years that I've had it. Not sure how old it was when I bought it.
Gin, I'm going to wait till it blooms to see what the flowers look like. I've waited so long, it would be sort of anti-climactic to ruin the surprise now by seeing a picture
For sure I'll post some pics when it blooms. I can't wait!!
