Self-sows where Deno gardened, but the seed ripens over a long period and is hard to collect.Seed Germination Theory and Practice, 2nd ed.

Toxicity is noted only where a source states it. No note here is not a finding of safety.

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 September 10, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on September 9, 2026.

  1. Dry storage

    Duration: 180 daysTemperature: 70°F 21°C

  2. Sow on the surface — do not cover

    Temperature: 70°F 21°C Light: light

about 6 months from start to sowing. Then 28 days to germinate.

18% germination in 28 days.

Two seeds of eleven. Deno calls the light requirement a small-sample result.

Lamium (Lamiaceae).. L. maculatum seems to require light based on a small sample as shown by 70L(2/11 in 4th w) and no 70D(none). These results are for seed DS 6 m at 70. This species self sows here, but seed ripens over a long period and is hard to collect.

Protocol 2

DerivedN. C. Deno, 1993

  1. Dry storage

    Duration: 180 daysTemperature: 70°F 21°C

  2. Sow and cover

    Temperature: 70°F 21°C Light: dark

about 6 months from start to sowing.

0% germination.

Nothing at all in the dark -- which is the whole basis for the light requirement.
