Following are some germination details I hope will be helpful:

1)Sow @ 18-22*C [~64-71*F] for 2-4 wks; then move to -4 to 4*C [24-39*F] for 4-6 wks; then move to 5-12*C [41-53*F] for germination.

2) Sow at 20*C [~70*F]. Seed germinates within 3 months.

3) 2nd edition of Norman C. Deno's book, Seed Germination Theory and Practice - Deno's research agrees with #3 method.

Based on the foregoing methods, it might be a good idea to split your seed into 3 batches and germinate as follows:

Batch 1: Wintersow (Refer to DG's Wintersowing Forum)

Batch 2: Stratify in the refrigerator for a month (or up to 3 months) before moving the pot to 70*F for approximately 3 more months

Perennial from the Alps in Europe. Spoon shaped leaves form light green rosettes and the whole plant including the flower can be covered in a white meal.

Flowers are held well way from the leaves and look like yellow velvet with a white 'eye'.

Flowers March to May and sometimes again in September.

Primula auricula is one parent to many hybrids that are available and have a colour range from green through to almost black.

Likes a well drained soil with protection from direct sun. Dislikes hot summers so will need shade during the hottest part of the day.
