Artemisia annua seeds do not require any type of stratification/vernalization. Please do be aware of the invasive potential of this plant before you decide to plant it.

Thanks Brandon. I have not grown it before, but I have a terrific place down in our meadow that I can till up and plant just for the Sweet Annie.. Then if it gets too invasive over time, we have a fellow that mows most of it for bedding hay and so I don't think it will be a problem...
Of course I will have to mark it off or the fellow will cut it down when he does the haying.. LOl

Thanks for letting me know..

Blessings,
Carolyn
