If you are looking for a novel groundcover, Meehan’s mint is the perfect choice. This deciduous herbaceous perennial groundcover spreads nicely in part shade and moist well-drained to average soils with foliage reaching only 1”-2” tall. In late spring it produces attractive lavender flowers with dark spots on upright stems 3”-4” tall above the foliage. Meehan’s mint spreads slowly, but is perfect for the summer garden when other plants have stopped flowering. This gem is an excellent companion to use with a wide variety of plants including Scutellaria serrata, Mitchella repens, Aquilegia canadensis, Carex plantaginea, Phlox stolonifera, Fothergilla gardenii, and Calycanthus floridus just to mention a few.
