Prunella vulgaris L. (commonly referred to as Heal-All or Self-Heal) is a flowering perennial native to much of Europe and western Asia. It creeps along the ground and roots itself with its stolons (like strawberries) and can tolerate many different soils and sunlight availability. In its native geography it is typically found growing in meadows and pastures, or alongside woodland margins. It is not very fussy where it grows.
It is also hardy to Zone 3 and will certainly take over a garden bed (which might be welcome in part shade). Like most Lamiaceae plants, its seeds are relatively easy to germinate.
Growing from Seed
Many studies have tried to find a benefit in using cold stratification and other means to promote germination, but the truth is these seeds just grow. They don’t need anything. They are non-dormant at dispersal, and all they need is light and room temperature. They should emerge in 5 to 7 days, and you should achieve a very high germination.
Seeds do tend to die off after 6-12 months, so be sure to harvest fresh seeds and don’t rely on old seeds for your precious gardening plans.
