No, if treated right, twice a year.

I gotta brag some more on this plant. Darn thing started blooming last year in Feb, has held at least one spike (up to 3 at a time) since, and I see a new spike that's probably a month away from flowering (just noticed today).
Gotta say, it looks like that's gonna make it more an entire year in flower.
I'm so glad they sent it (as a freebie), it's been a healthy plant for ten years now and flowering all except two of those years (my neglect). It was my first antelope!
