You can sow them now but Carrie Thomas (National Collection holder) suggested January in a cold GH with the last order I got from her.
If you sow now there are two possibilities, they might germinate quickly and you'll have tiny seedlings to see through winter, or they might not germinate til spring.
Trying to germinate them quickly in a heated prop or GH is not helpful for these, cold is what they want, it's what they get naturally
They don't flower in the first year
