Not to be confused with other species that are named mountain mint, this one is Pycnanthemum virginianum and is native to Ontario, Quebec, and New Brunswick.
What a great plant! And we had a huge swath of them this year, so we can share with you. This tough plant thrives in poor soil, spreads easily and is even deer-proof! On top of that it smells like mint from the flowers to the roots! The plant is actually more closely related to the wild bergamots than true mint, but if you like a fresh minty smell this will work just as well.
As with beardtongue the seeds are tiny; here they are shown alongside a peppercorn for size perspective. That makes them a bit more expensive, as it is hard to sort them from debris and you have to be careful when opening the package!
Cost is for 20 seeds; shipping to areas where it naturally occurs comes at no extra cost.
