This took a long time to go from bud to flower. I was surprised. (The post about the buds was 24 November, which was more than seven weeks ago.) On the other hand, it looks like the blooms are going to be spread out over a long period, so the plant will be blooming for an unusually long time, too.
If only the flowers were, y'know, pretty. Not that they're hideous; they're just not really big enough to be noticeable. Oh well.
