Where can I obtain Red Rariplia Mint in the USA? Does anyone sell it or perhaps an USA gardener would be willing to provide some? https://www.gardeningknowhow.com/edible/herbs/mint/care-of-red-raripila-mint-learn-how-to-use-red-raripila-mints.htm
I found some sellers by searching for this term, "Mentha x smithiana". Give it a try.
