Hello, all! I have two plants that my father picked up for me at a nearby farmer's market. When he asked the person selling them what they were, she didn't know! She explained that they had been sold to her as cuban oregano, but as they developed, it became obvious that they were not.
Well, when he brought it home, I did a bit of googling, and found out that there was a plant called "Vick's Plant" that is commonly confused with cuban oregano, and some of the pics matched, so I thought the mystery was solved. However, when dad went back to the farmer's market and told the seller this, she said she had some Vick's Plant, and that was not it either!
I wouldn't worry about it too much, but they don't seem to be doing very well. I've been treating them like my other succulents, and there's no obvious sign of pests, but they're rather droopy (though I took a few of the worst leaves off).
It smells of camphor, is quite fuzzy, and has pronounced veins on the bottoms of the leaves.
Plants in a species are kinda like brothers and sisters ...they all look similar but not identical. You can often find minor leave variations on the same plant at different stages of growth. I have heard the fragrance of Plectranthus amboinicus (cuban oregano) described as everything from minty oregano to minty turpentine...
I would certainly follow the care guidelines for Plectranthus until the plant attains a bit more size and flowers. Then you will be able to ascertain the proper species.
