Plant Profile: Stylosanthes biflora

Pencil Flower, a perennial wildflower belonging to the legume family, is indigenous to the central and eastern regions of the United States, thriving in dry woodlands, fields, and thickets. It is commonly found across North Carolina. This plant typically reaches heights of 0.5 to 1.5 feet, producing yellow, pea-like blossoms that appear from late spring through fall, albeit in limited quantities. Pollination is primarily carried out by bees, while deer and rabbits often feed on its leaves. Notably, there is some variation in the appearance of its leaves and flowers depending on the specific area.

Preferring acidic, somewhat nutrient-poor soils that reduce competition, Pencil Flower flourishes in full sun to partial shade. Although it is rarely cultivated and can be difficult to locate, it has the potential to be grown in naturalized settings.
