Helianthus atrorubens (Appalachian Sunflower)

Helianthus atrorubens, commonly known as purpledisk sunflower or Appalachian sunflower, is a striking native perennial sunflower not commonly cultivated. In nature it occurs in remnants of prairies and undisturbed sites, including open woodlands, old country roadsides and powerline cut-throughs.

This perennial sunflower is atypical of most sunflowers in that it grows low for part of the year, with large, rough spoon or spade-shaped leaves. When in flower, it shoots a single upright stalk reaching heights of 3 to 6 feet. The intensely bright yellow flowers, which bloom from mid to late summer into fall, have deep reddish-purple to dark brown centers (or disks). This contrast gives the plant its common name.

As a member of the Asteraceae family, Purpledisk sunflower blooms support an immense variety of pollinators, including specialists. It also serves as a host plant for various native moth and butterfly species, including checkerspots and painted ladies. In fall, its seeds are a valuable food source for birds such as finches and sparrows.

Because the species is low-growing (except when in flower) Purpledisk sunflower seems to appreciate being planted with medium to lower-growing plants to not be overshadowed, though we have found it to grow up around taller plants so long as there is sufficient sunlight. Examples include grasses such as Andropogon ternarius, Andropogon virginicus, Aristida purpurascens or Schizachyrium scoparium; and drought tolerant flowering perennials such as Symphyotrichum patens or Baptisia tinctoria.

We hope to introduce this beautiful and unique species to more landscapes and gardens. Its tolerance for dry, sandy, or poor soils makes it a great choice for restoration in degraded habitats, dry slopes, or sunny naturalized plantings aimed at boosting ecological resilience.
