Noteworthy Characteristics

Pycnanthemum tenuifolium, commonly called mountain mint, is somewhat misleading since the plant typically grows in the wild in dry, open, rocky woods, dry prairies and fields, along roadsides, along streams and in open wet thickets. An erect, many-branched, herbaceous perennial that grows 2-3′ tall and features extremely narrow, almost needle-like leaves and profuse terminal clusters of small, white flowers which bloom in mid to late summer. All parts of the plant emit a strong, mint-like aroma when crushed.¬†Pycnanthemums¬†have been used in teas.

A Missouri native plant that is found throughout the state.
