I been growing this plant for two years and it's one of my favorite, but I do not know what it is. My friend was the one who gave it to me and told me it was brazilian oregano, but I cannot find such thing, some people told me it is Cuban oregano but it is not.

Plectranthus, not sure which one.

There is one with a common name of Cuban Oregano but yours is not that variety. (synonym Plectranthus amboinicus)
Cuban Oregano (Coleus amboinicus)

Beautiful! Look at P. argentatus & forskohlii.

Thanks!!!
It is definitely th p. Forsksholii.
Do y'all know how to get it to seed.
The plant that has the flowers on it was from last year, and it never gave me seeds. Unfortunately the hurricane that passed by destroyed it, the plant without the flowers is one I am growing now from a cutting from the last plant. Do you need two plants to get them to seed?

Good question. I'd love to find one and experiment! Many of its' relatives in the Lamiaceae family seed copiously.

It does look a lot like Indian Coleus (Plectranthus barbatus) (Synonym P. forskohlii).
