There are many varieties of oregano. There are european members, such as Dittany of Crete (O. dictamnus), O. onites, O. syriacum, O. marjorana, O. heralcleotium; and those names alone seem magical to me.
There are varieties from the Americas including Lippia graveolens (Verbena family) and is usually called Mexican oregano. This is an interesting plant that I grew one year. There is also Poliominta longiflora (Mint family) and is grown for ornamental use.
I don't know what kind I have, but I think it is O. heracleoticum. It's been growing on the north side of the house in a (sort of) raised bed, which I think is a no-no. Still, I have a nice big patch, and I harvested it. I should have another harvest at the end of the summer. I air dried a bunch the other day, and put it in a jar today, and it smelled so good. That's what I love about herbs (besides the taste) - the scents are incredible.
When I was working - every summer my desk would have a large vase of flowers and another one of fresh herbs I picked from my yard - wild mint, chocolate mint, pineapple mint, Sweet Melissa (lemon balm), plenty of bronze fennel (smells of anise), a little rosemary maybe, and if the sweet marjoram was doing well, a huge sprig of that. People would pop by the desk just to rub the herbs and stick their faces in - using it for a stress reliever. Who does not feel better around flowers and herbs? Often I would share, and take co-workers around the hospital little cups of herbs for their desks.
My favorite ways to use oregano, besides the standard italian-goes-along-with-tomatoes way, is to rub a beef roast with oregano and garlic. Every Christmas, my mother would make a ham, a turkey, and a eye of round roast with oregano on top. I still love this flavor. Simply delicious.
On pork roast, I love to use oregano, sage, and garlic. The scent of a roast in the oven with these three herbs will drive you out of your mind.
Oregano is thought of as a flavor, not as a specific plant. Chemicals in these plants are in the Mint Family.
