Seed
Ontario Rock Garden Society states to sow their seeds at 20 C for 3 months followed by 4 C for another 3 months. Personal experience achieved germination by simply stratifying seeds for 8 weeks at 2-4 C.
Division
Plant is tap-rooted so division is not practiced.
Cuttings
Not generally practiced as the rosettes are essentially stemless.
