Pycnanthemum tenuifolium

Mountain Mint-Narrow-Leaved

Very narrow, mint-scented leaves form a soft, billowy, well-branched clump that adds beautiful texture to native gardens, prairie plantings and rain gardens. Blooming a bit earlier than P. muticum, terminal clusters of tiny, white flowers attract native bees, butterflies and beneficial insects. Can spread aggressively; root prune to prevent spread.
