Does wild spearmint grow in Colorado? Where is it most likely to be found?

The mint commonly called spearmint (Mentha spicata) is a pretty common weedy species in Colorado, found along streams in shady places. I've seen it in ponderosa pine forests near Boulder, and evidently it grows out in plains counties as well (see map below) in ditches and along streams.

Yes, right next to the weed they grow up there.
