This source reports three treatments. All are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

Start around March 21, 2027 for a May 3 last frost.

  1. Gibberellic acid soak

  2. Sow and cover

    Temperature: 70°F 21°C Light: dark

No stated waiting before sowing. Then 15 days to germinate.

100% germination in 12–15 days.

GA-3 in the dark beats light alone.

Protocol 3

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

Start around December 23, 2026 for a May 3 last frost.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  2. Sow and cover

    Temperature: 70°F 21°C Light: light

about 3 months from start to sowing. Then 13 days to germinate.

70% germination in 4–13 days.

2% germinated during the cold period. In the dark the figure after the shift is 56% rather than 70%.
