I wouldn't know the best way of germinating these seeds, but I got good germination last year just by plunging ahead without information, and hoping for the best. I chilled the pots in the cold room for 3 weeks, and then germination started in 4 days after they were brought into room temperature. (Given the brevity of the chilling period, I sort of doubt that any chilling was actually necessary.)
The seedling were planted out in a tufa bed. I'm eagerly awaiting spring to see if they survived.
