Organic Greek Oregano Seeds

Greek Oregano is a spicy aromatic herb. It's great on pizza, in pasta sauces and salad dressings. It can be grown in pots or as a border to walkways. oregano is perennial in zones 4-8. However, I'm in zone 6b and it's behaved as an annul for me in a 17 gallon pot. I like to interplant it with basil. If it comes back as an annual, it does spread out a bit, it is part of the mint family.
