Pycnanthemum muticum – Broad-leaved Mountain-mint

“Pycnanthemum muticum, commonly called mountain mint or short-toothed mountain mint or clustered mountain mint, is a clump-forming aromatic perennial that typically grows 1-3’ tall. It is native to Eastern North America (Maine to Michigan to Illinois and Missouri south to Florida and Texas) where it typically grows in grassy open places, meadows, fields, low woodland areas and occasionally in dry upland woods, but not in alpine areas as somewhat inaccurately suggested by its common name. In Missouri, it is only found in the far southeastern corner of the State.

Product Description

“This densely leaved mountain mint features dark green leaves which have a strong mint-like (spearmint) aroma when crushed. Branched stems (mostly square in cross section) are clad with nearly sessile, ovate to ovate-lanceolate, acuminate (pointed), dark green leaves (to 2 1/4″ long) with round to heart-shaped bases and toothed margins. Plant foliage is topped in mid to late summer by a bloom of two-lipped tubular pink flowers (each to 1/2″ wide) in dense flat-topped terminal (sometimes axillary) clusters, with each cluster being subtended and highlighted by a pair of unique and showy silvery fringeless leaf-like bracts located near the base of the cluster. When planted in groups or massed, the silvery bracts give the entire planting the appearance of being dusted by a white powdery snow. Flowers are attractive to butterflies and bees.” (Missouri Botanical Garden)

Summer Shipping Concerns

Please expect some delays in shipping during summer months!

Shipping perishable items in the heat of summer can be tricky to say the least. Our goal is to try to get your plants to you in the best shape possible.

This means we may hold off on shipping items during periods of excessively high temperatures to give your new plants the best chance of surviving their journey in good shape.
