This source reports three treatments. All are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

Start around December 21, 2026 for a May 3 last frost.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  2. Sow on the surface — do not cover

    Temperature: 70°F 21°C Light: light

about 3 months from start to sowing. Then 15 days to germinate.

38% germination in 4–15 days.

Both the cold period and the light are needed: nothing germinates without either one. Most of it comes up in the first 4-6 days.
