Hyssop-leaf thoroughwort (Eupatorium hyssopifolium) produces upright stems somewhat sparsely clad in short, narrow, grayish green leaves. In late summer through early fall, the 2- to 3-foot-tall stems are tipped with flattened clusters of many tiny, white flowers. The blooms are favored by a variety of pollinators and beneficial insects. Hyssop-leaved thoroughwort spreads moderately by underground rhizomes and looks right at home in a meadow (where mine grows naturally, on a dryish slope) or in a naturalistic border with grasses and other late-flowering perennials. Provenance Milford Township, Bucks County, PA. Full sun to light shade. Perennial; Zones 4 to 8.
2021-collected seeds sold out. I hope to collect again in late October 2022. At least 20 seeds.
