Propagating orchids from seed

I have a friend who grows various Cypripediums very successfully (he has 
AOS awards to prove it) and I'll ask him that question.

But I suspect not, unless your plants came from the wild originally. 
Most Cyps in gardens now are lab grown (thank goodness!) from seed 
without mycorrhiza.

A few orchids can be grown from seed pretty easily as you describe, or 
even without sterile culture, and one (Cynorkis fastigiata, not hardy) 
is even a charming weed in my greenhouse. But I don't think I know 
anyone who's managed to grow Cyps that way. My friend has told me 
they're slow and often recalcitrant even in sterile culture.

But if you're pretty sure the pods are pure C. monantum, I'm sure 
someone (I'll suggest Troy Meyers, the Meyers Conservancy) would flask 
it for you and give you some plants back for free.
