I find the closer to a "wild" a variety is, usually the more vigorous the plant. Named cultivars, variegation, and lots of extra breeding for some characteristic make plants less robust in my experience. Example, those "flavored" mints have croaked for me without so much as a wimper but your unnamed, generic mints persevere no matter what I do to them.

I've only planted spearmint so far, but I can't imagine any of the other ones being MORE invasive! LOL

My Chocolate Mint is extremely invasive. It has vines trailing in every direction. I really should of planted it in a better spot.

My chocolate mint is extremely evasive as well. Started with one plant and now have dozens within only a few months. Spearmint is extremely evasive as well.

:"Invasive" is a very broad term. However, considering that spearmint isn't native to NA but it's now found almost everywhere , I'd certainly call that "invasive"

I found a peppermint while hiking happily choking a spring in Arizona in the pine forest above the Mogollon Rim. Now that's getting around!

INVASIVE BY ROOTS is really invasive. I do not consider multiplying by seeds to be invasive because one can simply pull them out just like we treat weeds . But you cannot do this with mints.

So I consider all mints that I know, INVASIVE. That is why it make sense to contain them in pot(s).

I would have said Orange, before I got a chocolate mint..

The least rampant seems to be the Pear. All the others fall somewhere in between. ..but I'm just now starting to plant them in the ground in the places where I want them to go wild, so I can't say for sure. I THINK Orange may still win.

Chocolate mint is a definite runner up (pun intended :o)
