Olga, your photos are outstanding as always. Thanks so much for posting them here for us to share.
I can understand Mr Lang's attitude about every new plant having known parents but when a large part of the world's alpine growers have no access to any of these superb plants, surely seeds could be distributed. It's not as if any seedlings would ever compete with those already in cultivation. On behalf of many growers in the southern hemisphere, I would be interested in contact with anyone willing to share seed, either from the UK or from Europe. Some, we here would not be allowed to import but many others would.
