Worth knowing

This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

  1. Sow outdoors and leave it

    Up in April.

No stated waiting before sowing.

36% germination.

This source doesn't state how long step 1 lasts.

Fritillaria (Liliaceae). This genus germ. primarily at 40. Sometimes this had to be preceded by a cycle at 70 making the species a 70-40 germinator. The seedlings did not always develop, and it is probable that this was the result of shifting them to 70 too suddenly. More study is needed on this problem. Some species showed intolerance to DS, particularly F. pudica germ. best in outdoor treatment (36% in April) and less in 40-70- 40(20% in 2-9 w). Germination failed when sown at 70.

Protocol 2

DerivedN. C. Deno, 1993

Difficulty High Rated by us, not by the source.

Start around August 6, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on August 5, 2026.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  2. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

  3. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

about 6 months from start to step 3. Germination happens during step 3, in 63 days.

20% germination in 14–63 days.
