Linum sulcatum, commonly known as Grooved Yellow Flax, is a perennial herb that is native to North America, specifically found in prairies, glades, and open woodlands of the central and eastern United States, as well as in parts of Canada. It typically grows to a height of 12 to 18 inches (30 to 45 centimeters) and is characterized by its narrow leaves and grooved stems. The plant produces showy, bright yellow flowers from late spring to early summer, which are particularly attractive to various pollinators.

Grooved Yellow Flax is valued for its delicate, cup-shaped yellow flowers and its ability to thrive in a variety of soil types, although it prefers well-drained soils. It is often used in wildflower gardens, meadow plantings, and for naturalizing areas where its low maintenance and drought tolerance are beneficial. In cultivation, it requires full sun to part shade and can tolerate dry conditions once established. While not commonly found in the nursery trade, it is sought after by native plant enthusiasts and for conservation purposes due to its status in the wild.CC BY-SA 4.0
