HerbDoc has some thoughts on a different species of oregano:
My go – to herb garden in Connecticut always offers something new and unusual to add to my ever growing collection. On my last trip, I purchased Cuban variegated oregano, Plectranthus amboenicus variegata. This popular herb is used in both Spanish and Cuban cooking. I’m told that it is delicious deep fried in batter but I haven’t tried it yet!
I can say that it has a heady oregano aroma! Its fleshy oval leaves have very distinctive shallow white edged teeth around the perimeter. It is said to prefer full sun and rich well-drained soil and grows to 12 inches tall and some 20 or so inches across.
Since it’s a tender perennial, I intend to grow it with my other herbs that winter indoors – the bay, lemon verbena and a few smaller rosemaries.
