This is one of the keikis from my Summer '09 project plant.
Growing in a north facing window; potted in sphag in a tiny clay pot. Nearly 1" bloom (vertically), on a plant only slightly taller (about 1-1/4")
These can get successive blooms off a spike for a while, so there is another bud developing on this spike as it has this bloom on it. There is also another spike coming along on the other side of the plant
Usually fragrant (a pungent, but not unpleasant, citronella-like fragrance) - but I haven't caught any fragrance off this bloom, but perhaps need to check earlier in the day
Unlike most other people, I don't do anything special for humidity for these guys. The only time that was a problem was with the multiple keikis on my original plant - in summer, the keikis looked dehydrated, so I would spritz their roots often, which led to the potting media being too wet, and the roots of the parent rotted

So, that is why I removed the keikis a while back.
The parent has been growing well sans roots for a few months, and recently started new roots
Thanks for looking
