In addition to being a good garden plant with the narrow leaves and small white flower clusters Slender Mountain Mint stands out because of its above average attraction for pollinators. Plant in a perennial border, pollinator garden, rain garden, or near the vegetable garden to entice pollinators. The aromatic plant with shallow rhizomes is more aggressive than other Pycnanthemums so needs root pruning to keep from spreading. This is also called Narrow Leaved Mountain Mint and is native to Cape Cod.
