It looks like it might be the Basil, there are a number of different cultivars that have a similar leaves. I am looking at the growth-point top right and that looks more like a basil than a mint.

As to a cross of the two - why not?

Thanks a lot Guys, Much appreciated

I will also ask some experts to smell it and keep you updated, yes there are chances of cross pollination, Thanks

It does not look the any of the holy or sweet basil I've grown so I'm not sure it is basil. I know there are other vegetables, greens, and herbs grown in your part of the world that we may not be familiar with. I grew jew's mallow (Corchorus olitorius) a few years back. I'm not saying that is what this is, but most people reading here wouldn't be familiar with that at all. (For others, it is a Middle Eastern plant used as a green, herb, and fiber source.) I'm just saying that I think it is a plant or even a variety that is more endemic to your location. I think that is why you have gotten limited response here and on Name That Plant. Any local gardeners you could ask?

Mentha (mints) and Ocimum (basils) can't cross. They are in different Genera. Intergeneric hybrids are very unusual in nature.

I just noticed the serrated edges. So it's not Holy Basil.

A nearby vegetable stand sells sweet basil through the winter that has serrated leaves just like that. In the summer basil looks much more bubbly. I suggest you eat a leaf and tell us how minty it tastes. Or just shred it with olive oil, salt, pepper, and pine nuts, and call it a day---a pesto day. That's what I would do.

Thanks a lot guys, much appreciated, sorry guys this mint is mountain wild mint that's why no one is familiar with it, maybe grows well in desert climate (Qatar) the plant was also looking more like basil, sorry for the confusion.

It is actually a mountain mint. But It looks different from those in this picture below, it was trying to form flower at one of it topmost tip. hope I can use this like normal mint, it is extremely minty smell and this link below extremely praises this wild mint with so many medicinal benefits, I hope this is the same variety.

I remember planting it long time ago from cuttings but they looked extremely different while planting from cuttings

Glad you got an answer! Thanks for letting us know.

All Pycnanthemum (mountain mint) species are native to North America - that was the genus you linked to. I've grown two or three Pycnanthemum species and they do not look like your plant. Do you know the genus of your mountain mint? I'm sure your native "mountain mint" is of a different genus. The species is important to know for how and more importantly if you can safely use it as an herb.

It looks like Thai basil. Does it have an anise smell?

Dear Mimbraga It is actually a variety of mountain mint, special to this place, Thanks

Fatamorgana, they LOVE their mint tea in Qatar. I wouldn't doubt if it weren't introduced and just has a different form for adaptation to the arid environment. Similar to how many Aroids have different forms depending on the contitions.

Mint is an incredibly adaptable edible vegetable (aka weed).

The Mint tea drunk in the Middle East and N Africa is made with Mentha species, not Pycnanthemum.

Dear Floral yes you are absolutely right.

This is mountain mint is not for consumption I think unlike other mints, thanks

Pycnanthemum virginianum and P. incanum are both usable for tea. My mountain mints, I grow both of these, are in bloom right now.

That's really good news, I will start using them for tea, Thanks Dear Fatamorgana

Maufie, just be sure to try just a little bit at a time like maybe 1mmx1mm piece and wait a few hours or a day to see if you have any reactions to it (vomiting, diarrhea, hallucinations, anaphylaxis, etc).

Then try a little bit bigger piece each time, waiting in between each time you increase the amount you try.

This is a good rule to follow anytime you try something that you haven't tried before.

It will probably be fine, but each person reacts differently to different plant compounds.
