Would you happen to know where I can purchase spearmint seeds? Preferably in the Toronto area or at least within Canada. I need to find seeds for mint with the scientific name Mentha arvensis.
Wild or Field Mint (Mentha arvensis) is a common native plant. You may find references for suggested seeds resources in the link below: https://www.torontomastergardeners.ca/index.php/askagardener/looking-to-buy-some-plant-seeds/
Please note that when looking for this particular seed not to confuse it with Spearmint (Mentha spicata) which is quite invasive.
Good luck with your search.
