Jim, the Anguloa might like your OC. Just make sure it receives less water in Winter, so it drops the leaves /adheres to the seasons.
Regarding the Dendobium smilliae - perhaps it makes a difference that I started out with a large/mature plant already. I am happy I bought it!
And - the Sarcoglottis sceptrodes looks great. Mine wants to drop a few older leaves, but I see new, curly rosettes starting up again. Good plants to have.
Those Psychopsis are amazing in the re-blooming department. I slowly wish I would see some new growth on mine....
Oh yes and Happy Fireworks Day to you ALL!
