It has the characteristics of lemon balm / mint, with square stems, but it doesn't have the lemon / mint smell. Also, its leaves seem to be more rounded, where lemon balm leaves have more of a pointed tip.

    gardening.stackexchange.com is also a very good source for identifying plants. If you move this question to that stack, please include the location of the plant.

I assumed this plant was Lemon Balm, but without the smell, I am now certain it is rather Red Deadnettle (Lamium purpureum)

It is definitely in the Mint Family (Lamiaceae): Species in Lamiaceae are herbs or shrubs with distinctively 4-sided stems.

This is however, not American Cornmint, better known as Wild Mint or Mentha canadensis

Here is an example of Wild Mint or Cornmint, notice the difference in leaf shape:

Without the smell however, this plant is most certainly Red Deadnettle. It is extremely similar to Lemon Balm, but lacks the smell:

This looks like American Cornmint to me. If you still have access to the plant, pinch one of the leaves and you should be able to smell if it is a mint or lemon balm.

  • Simply by appearance and my familiarity with the plant.
