I am trying to start Fritillaria atropurpura and F. recurva from seed. The seed has been placed in zip lock bags with damp vermiculite and perlite in the refrigerator. The F. atropurpura have sent out shoots. At first I thought they were roots but they seem to look like stems. When do I pot them up? Is this first growth roots or stems? The F. recurva has not done anything yet, about 60 days in the refrigerator. Any advice? Sunset zone 9. Jim B
