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, 1993Difficulty Low
Start around March 22, 2027 for a May 3 last frost.
Sow and cover
Temperature: 70°F 21°C Light: either
No stated waiting before sowing. Then 14 days to germinate.
100% germination in 14 days.
Every seed, in a fortnight. Neither light nor GA-3 changed anything. Deno's seed was garden hybrids, not a named species.
Protocol 2
DerivedN. C. Deno, 1993Difficulty Low
Start around February 1, 2027 for a May 3 last frost.
Cold moist stratification
Temperature: 40°F 4°C Light: either
Germination happens during step 1, in 63 days.
100% germination in 49–63 days.
Cold gets there too, and takes two months longer about it. Deno's seed was garden hybrids, not a named species.
How each step is done, in Deno’s words, and what Verified and Derived mean.
