Dyschoriste oblongifolia, commonly known as Oblongleaf Snakeherb or Twinflower, is a herbaceous, rhizomatous perennial that is deciduous in nature. It is native to open woodlands, savannas, and prairies in the southeastern United States. The plant typically grows to a height of 10–50 cm (4–20 in) and is known for its lavender flowers, which bloom from June to August. These flowers are subsessile, often appearing in pairs, with five lobes, four stamens, and a style 1.5 cm long, making them quite showy. The foliage is also attractive, with leaves that resemble the bracts surrounding the flowers.

Oblongleaf Snakeherb is valued for its adaptability to a range of soil conditions, from acidic to slightly alkaline, and its ability to thrive in sandy, loamy, or clay soils. Its high drought tolerance and low maintenance requirements make it an excellent choice for gardeners seeking a resilient groundcover. It is also used in butterfly gardens as a larval host for the common buckeye butterfly, contributing to local biodiversity. In cultivation, it prefers full sun to part shade and requires well-drained soil with medium to low water input. While it has low salt tolerance, it is otherwise a hardy plant with few disease or pest issues.CC BY-SA 4.0
