Eupatorium hyssopifolium

According to the Mount Cuba Center:

“Hyssop-leaf thoroughwort (Eupatorium hyssopifolium) is a member of the Aster family and attractive both in bud and flower and a perfect complement to a grassy meadow. The buds show color for a few weeks before ultimately opening, producing clouds of tiny white flowers from late summer into autumn atop 1-3’ tall stems. The very narrow leaves are whorled around the stem lending itself to a very finely textured plant. 

Hyssop-leaf thoroughwort grows in a variety of soil types but requires good drainage. This underused perennial is extremely attractive blowing in the wind with grasses and perennials including little bluestem (Schizachyrium scoparium),  broomsedge bluestem (Andropogon virginicus), black-eyed Susan (Rudbeckia fulgida),  smooth aster (Symphyotrichum laeave), and spike gayfeather (Liatris spicata)Zones 4-8.”

The entire plant is anti-venomous and may be used as a remedy for bites of reptiles and insects by brushing and applying to the wound”.

Hyssop has been used in folk medicine for centuries for stimulation of the circulation and for treatment of a variety of conditions including upper respiratory illness, asthma, cough, sore throat, intestinal infections, gastrointestinal upset, gall bladder disease, poor appetite, urinary tract infections and dysmenorrhea.
