Martin just handed over his whole collection to someone else and is now left with about a thousand heuff-seedlings and a lot of space to grow various flowers on, as he wrote.
He gave me the contact of a guy at the Federal Office of Cultivars, but as it seems they concentrate on kind of plant "patents", which is not what I intended and which far to expensive for me as I don't want to become a commercial semp dealer to get the money in again.
As it seems, the office contacted Martin in the past to get his expertise on pending semp "patents", not the other way round...
Let's see, what I can find out on Wednesday after tomorrow's bank holiday...
