Protocol 1
DerivedN. C. Deno, 1993Difficulty Moderate
Start around February 1, 2027 for a May 3 last frost.
Cold moist stratification
Temperature: 40°F 4°C
33% germinated at 40 itself, in 7-9 weeks.
Warm moist stratification
Temperature: 70°F 21°C
A further 29% in 6-10 days after the move.
Germination happens during step 2, in 63 days.
33% germination in 49–63 days.
Start cold. A third comes up at 40 and another 29% after the move to 70.
This source doesn't state how long step 1 lasts.
