Aromatic native woodland perennial for half shade or light shade.
Loose clusters of pale yellow flowers in early fall. Crushed leaves have citronella-minty aroma and can be used for teas.
The roots were formerly used for treating urinary and kidney problems (as astringent).
Best for half shade or light shade garden.
Blooming Time: late summer- mid fall (about August-September)
Size: usually 2-3' tall and 2' wide clumps
USDA Zones: 4 to 8
Culture: partial shade, dappled shade. Prefers soils with some organic matter or humus rich. Moderately fertile to fertile, slightly acidic to slightly alkaline (pH 6.8-7.2). Grows well in sandier or rocky soils and clay. Avoid waterlogged soils.
Moisture Needs: average (medium), medium-moist, medium-dry
Origin: native to deciduous woodland in the eastern part of USA and Canada (including the southern states like Florida). Rich woodlands, upland woodlands, wooded areas, river valleys (often on rocky soils). Often in oak-hickory woodlands or beech-maple woodlands (often where the sandstone bedrock is rather close to the surface). See the BONAP distribution map.
Deer/Rabbit Resistant: yes / yes
Attracts Butterflies or Pollinators: no / yes - offers nectar and pollen. The major pollinators are bumblebees. Host plant to larvae of a couple of the gall flies, some aphids and larvae of several moths (Horse-balm Sun Moth, Yellow Stoneroot Borer Moth, Dark Stoneroot Borer Moth, Stalk Borer Moth).
Attracts Hummingbirds: no. But the seeds are eaten by the Bobwhite Quail, and possibly other birds.
Pot Size: square 3.5" x 4" deep perennial pot
Plant Combinations: For shade, hlaf shade beds, woodland gardens, pollinator garden, herb gardens. Can be combined with any half shade or light shade tolerant plant - Actaea (Cimicifuga), Alchemilla, Anemone japonica, Bergenia, Brunnera, Dicentra, Digitalis, Epimedium, hardy Geranium (G. maculatum, G. phaeum), Geum, Helleborus, Hepatica, Hosta, Iris cristata, Lathyrus vernus, Persicaria, Phlox divaricata, Phlox stolonifera, Primula, Polygonatum, Pulmonaria, Salvia koyame, Scutellaria, Stylophorum, Tricyrtis, Uvularia and ferns. Looks wonderful with more fine structures of grasses like Carex (both narrow and wide- leaved), Chasmantium, Deschamspia, Hakonechloa, Hystrix, or Melica.
Goes well with bulbs (Anemone blanda, Muscari, Narcissus) and native spring ephemerals like Dodecatheon, Mertensia, Jeffersonia, Sanguinaria, Trillium and others.
