This popular wildflower is one of the very best for pollinators, supporting a diverse group of native bees and butterflies. It is showiest in late summer when the entire plant appears to be covered in silver dust due to the showy bracts. Its dark green, mint-scented foliage spreads slowly by rhizomes but is easily controlled. Tolerates clay soil, heat and mild drought.
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.
