Downy Goldenrod

Solidago petiolaris (so-li-DAY-go pet-ee-OH-lair-iss)

Family: Asteraceae Native Herbaceous (3-15 ft)

Downy goldenrod is a native perennial in the daisy family (Asteraceae) that is found in the southeast and south-central United States and in all areas of North Carolina. The genus name comes from the Latin term solidus, meaning “to make whole”and referring to the use of goldenrod by native Americans for medicinal purposes. The specific epithet refers to the presence of petioles. Plant it in slightly acidic, moist to dry soils with good drainage and in sun to partial sun. It can grow 1 to 4 feet in height and may need to be staked. Propagation is accomplished with seeds. It has striking yellow flowers in clusters that attract a variety of pollinators and beneficial insects. It blooms earlier than most other goldenrods, in late summer to fall when nectar plants can be in short supply. Use downy goldenrod in a native, butterfly or pollinator garden and in woodland, meadow and other naturalized areas. This is one of the 20 key pollinator plants that should be blooming in August for the Great Southeast Pollinator Census 2025. Insects, Diseases and Other Plant Problems: No significant problems.
