grow these orchids in living sphagnum moss. moss should be kept fluffy. also will try pumice as a growing medium, but in my opinion sphagnum is perfect.

Actually this is considered for a beginner who is interested in wild orchid cultivation in Japan. It is distributed (almost) throughout Japan. Also found in Korea, I believe.

Seeds of P. radiata can germinate on the surface of water, so no symbiotic relationship is neccessary upon germination. However, such a relationship is required for a subsequent growth.

Not for beginners.

A terrestrial orchid from seasonal bogs in Northern Japan, this beautiful plant has very definite likes and dislikes.

Will not tolerate dry heat above 30 degrees Celcius.
In growth, will not tolerate even a day's worth of dryness.
In winter, must be dry, or bulbs will rot.
Produces copious seed, but seed needs specific symbiotic bacteria to germinate. Tricky. Live spagnum moss a plus.
A hundred to one venture. Interesting, eh? ;-)
