This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty High Rated by us, not by the source.

Start around December 15, 2026 for a May 3 last frost.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

    2% came up here, at 10-12 weeks. Deno gives no length for this period; three months is his standard cycle.

  2. Warm moist stratification

    Temperature: 70°F 21°C

    A further 10%.

about 3 months from start to step 2. Germination happens during step 2; time not stated, 21 days assumed.

10% germination.

2% in the cold and 10% after the move. The better of two poor routes.

Protocol 2

DerivedN. C. Deno, 1993

Difficulty High Rated by us, not by the source.

Start around March 15, 2027 for a May 3 last frost.

  1. Warm moist stratification

    Temperature: 70°F 21°C

    9% here.

  2. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

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

  3. Warm moist stratification

    Temperature: 70°F 21°C

    A further 2%.

Steps after step 1 run on after germination.

Germination happens during step 1; time not stated, 21 days assumed.

9% germination.

9% at 70, then 2% more after a cycle. Neither route gets this one far.

This source doesn't state how long step 3 lasts.
