Got some Coulter's Matilija Poppy seeds a while back from a native seed supplier and I know they are difficult to germinate, so have been looking at various guides. Saw many references to exposing them to smoke from pine needles/etc. Finally came across one that recommended liquid smoke as an alternative (as long as it is just water and "smoke").

Anybody have experience using liquid smoke for helping seeds germinate? (or real smoke)

I found the idea for the poppies from this page: (was looking for alternatives to burning pine needles to smoke the seeds)

Dilute the liquid smoke in a ratio of 1:10 with distilled water. Submerge the matilija poppy seeds in the solution for a full 24-hour cycle to ensure the liquid penetrates the dense outer shell.

This soaking period acts as a chemical scarification, softening the lignified exterior while simultaneously delivering the growth hormones directly to the embryo. The results of this treatment are statistically significant for any serious grower.

I did find some mesquite liquid smoke that is just distilled water with the smoke "essence". When I checked online for the one I purchased, I did see somebody in the reviews mention that they used it for seeds.
