R. asiaticus seed definitely doesn't have to be fresh to give good
germination.  I've had successful germination (about 75%) from seed that
was at least two years old, and stored at room temperature.  My problem was
that the plants seemed to stop growing after they produced a few true
leaves.  This may have been because they germinated in the spring, and
their growth was stopped by warm weather.  Seed appears to germinate best
with warm days and cold nights, but I'm not 100% sure of that.
I don't know of any commercial source for seed or tubers of the true
species.  It is occasionally offered on the North American Rock Garden
Society seed exchange, but not this year.
Incidentally, Polunin and Huxley, in Flowers of the Mediterranean, describe
the flowers as "often scarlet, but may be white, yellow, or orange."  The
book has a great picture of the scarlet version on the cover.
