About this species:

The mountain mint can be found in moist soils such as in meadows, swamps and along streams and ponds.

This is an erect, many-branched, herbaceous perennial that grows 2-3' tall and features narrow, toothless, tapering leaves and profuse, somewhat flat-topped, terminal clusters of small, white, 2-lipped flowers which bloom in mid to late summer.

Its leaves are simple and alternating on the stem with a mint fragrance.

It has a long bloom time of 4 or more weeks and is highly attractive to pollinators. Its light green and narrow leaves and smaller white flowers look nice when combined with plants with large leaves and bold colors.
