Common type of Mint?

[Amos Ziegler]

Have a homeowner trying to determine the type of Mint this is.

[Byron]

Yes.  Thanks!  This volunteered in my raised bed garden next to my basil, marjoram, and rosemary to the point of crowding them.  Wondering if it is usable and for what or if I should remove.

Mints are hard!  Check out https://www.michiganflora.net/genus.aspx?id=Mentha for true mints, and https://www.michiganflora.net/family.aspx?id=Lamiaceae for the whole mint family.  You can also reach out to your local MSU Extension and/or Master Gardener program for help.

If it does end up being something you want to keep, I'd suggest keeping it in a container to help save your other herbs.  Avoid putting clippings in the compost, as this can spread the plant in your garden or in natural areas.
