Well here we are, two and a half months later...
I thought I'd note my observations on this plant's blooming habit. The spikes grew very slowly over the course of the past two months, reaching a length of about 6 cm and swelling into a teardrop shape (can be seen in photos below).
Then, last week, I noticed the buds had suddenly split open at the ends. From that point they have grown with surprising speed, doubling in length to about 12 cm in just a few days. The long strands are starting to unfurl and this "pom pom orchid" is finally,
finally coming into bloom!
