Has anyone had any success in the propagation of a Betulia. If so,
would you kindly share your method.

Incidentally, I know where and how they are grown and that any seeds
from them would be sterile.

Emrys,
Do you mean Betulia~ Begonia x hiemalis var. Betulia, or Betula~ Birch?.
Begonias were mentioned a few days ago with a Google guide to culture and
propagation.
