Thanks for commenting James. The plant has 2 spikes.
Each spike has 2 buds and it seems to be a sequential bloomer. On 1 spike 1 of the buds blasted. This is still a very young plant, and I'd actually prefer it grows a few more "blades" before it produces more spikes. The flowers are quite large for the size of the plant, so it seems quite possible for it to bloom itself to death. I've never seen a pinkish one ......... I'll be hunting for one of those now!
