Nice link find,
and indeed you have my respect and admiration.
Not everyone here would be respectful enough of a plant/life form,
to give up the opportunity to "get" one, in order to help it have the best chance of survival.
(Which now really puts the pressure on me!)
In another thread currently running here on TF, there is discussion about someone wanting a jellyfish (or more!) and how they don't even have a clue on how to raise & care for it. While plants are often looked at as slightly "lesser/lower" than animals, they indeed are living creatures, possessing the same life force (*) that imbues us with our own living consciousness here.
So I go from seeing that person's attitude, next to yours.... Difference is like night & day to me! (I wish it were for most people here, however.... well, at least most of the people here have an appreciation for these plants, unlike most of the people in this world.)
Anyway, I would think that if you are in AK, you would be able to gather some native soil from an appropriate location, and give the seed an even better chance than I!
(I saw a listing in that info for Cypripedium parviflorum var. pubescens flat-petalled form from Red Deer, Alberta... I know its not close, but you are closer to that location than I am! And I am sure similar orchids grow out your way somewhere. Even where I live that are a few places where similar orchids grow (if you can find them). (I realize I am being a bit "rudimentary" in presenting this outlook, however in my experience with nature, ...it is a lot more adaptive & tolerant than we often realize, and you sometimes don't know what's really possible until you try.) Even here, what one person claims "can't be done", another person discovers it can, or has even been doing for years!
Well, if I do get the seed, I will at least try to split it with you, if there is enough volume-wise to do so. (1/2 a speck of dust is a bit small to manipulate!) I figure it is better to have 2 opportunities to succeed than only one!
(Give it some thought....) I can't think of anyone more deserving to try... than someone who is actually concerned!
Otherwise I will do my best. (Just because I get other things to grow at times doesn't mean I don't also fail at it at times too.)
Again, nice find on the info, and thanks again for the opportunity.
