Cultural tips on specific genera by Yin-Tung Wang, Ph.D.
Question: While in Corpus
Christi I purchased a Nun Orchid, Phaius tankervilleae, at a local
nursery. Have you ever tried to grow these in the Valley? The plant is
really neat. Richard Lehman
Answer: Richard,
The nun orchids do fine and bloom well in South Texas, as long as they are
partially shaded and given plenty of water. They prefer moist medium at all
times. Otherwise, leaves die back quickly. Yin-Tung
Quick question: Do you think
I would be able to grow a Stenorrhynchos speciosum in the Valley (in
the greenhouse)? According to Orchid Wiz it requires a bit cooler temps than
we have here, but sometimes plants seem adaptable. Marianne

Answer: Marianne, Stenorrhynchos
speciosum is native to 1800 meters (6000ft) of
elevation, it must be grown close to your cooling pads in the summer. Keep
it as cool as you can make it. It likes moist medium throughout the year.
So, never allow the medium to dry out completely. It may be a good idea
to add some peat to your standard bark mix. Feed lightly. I would shade
it. The bright red flowers often come around Christmas. Yin-Tung
