How large are the plants? Fantastic color and you can clearly see the influence of the Epidendrum.

Yes, the plants do show the influence of Epidendrums. The two year old plants are currently grown in 4-inch plastic pots in bark media. The mature plant stalk is about 10 inches tall (measured from top of media). The inflorescence extends about 8 inches from the top of the stalk. I expect the plants and inflorescence to be taller the next time around.
