This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Very high Rated by us, not by the source.

Start around June 19, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on June 18, 2026.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

    Deno gives no length for this period; three months is his standard cycle.

  2. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

  3. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  4. Warm moist stratification

    Temperature: 70°F 21°C

    One seed of eight, here.

about 9 months from start to step 4. Germination happens during step 4; time not stated, 21 days assumed.

12% germination.

One seed of eight, after a year of cycling. This plant is barely germinable as Deno had it.

  2. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

    Nothing further in the cold.
