Hyssop-leaved Thoroughwort Eupatorium hyssopifolium

Hyssop-leaved thoroughwort is a herbaceous perennial in the aster family ( Asteraceae) native to the eastern and central United States. It is native to dry, sandy or gravelly woods, fields, salt meadows and disturbed areas.

The plant grows in full sun to partial shade in a variety of well-drained soils but does best in dry, sandy soils. It is tolerant of drought, deer, salt and urban conditions.  Hyssop-leaved thoroughwort will grow 1-3 feet tall with a 1-2 foot spread with a clumping habit. It spreads by rhizomes and self-seeds. Deadhead after flowering if self-seeding is not desirable. Otherwise, leave the seedhead on through winter for the birds.

Flowering occurs from summer to fall with abundant clusters of small tubular disc flowers and no ray florets. They are magnets for pollinators. The leaves are narrow and grass-like and occur in whorls of 4 along the purplish stems giving it a fine texture.

Use this plant in naturalized areas such as meadows and fields. It can also be used in the pollinator garden and planted in difficult areas of the yard such as dry slopes and dry sandy areas. It pairs well with native grasses and is attractive blowing in the wind among them. Add some tall yellow flowers and you have a lovely naturalized area.
