I was given some potato mint earlier this year by my friend Josh at H.E.A.R.T. (If you haven’t seen it, you should see the tour video I filmed there a couple of years ago).

Here’s the first harvest:

Not a lot of tubers there; however, the plant was only in the ground for half the year. It also seemed to set more tubers right in the garden path along its runners than it did at the base of the mint itself.

There’s more on the fascinating mint potato here.

The leaves don’t have much of a mint smell but are apparently edible. It’s also totally NOT frost-tolerant, as you can see by the wilted mess in the video. That was caused by a night near freezing, not even below!

I may have gotten the Latin name wrong in the video. My type is probably rotundifolius.

Not sure. Really neat plant, though.
