I am a member of the Trillium forum and I also receive seeds from there and I have also made some Trillium from seeds, for example, nivale and several colours form of erectum.
Anthony I know that it is quite special Trillium I'm looking for and I do not think there are many who grow the Asian species.
In my collection I have a few of the Asian species, but it is the more common, for example camschatcense, tschonoskii, apetalon and smallii.
I would like to hear, if there are other members who grow other of the Asian species.
