Sabatia angularis
This native biennial wildflower forms a low rosette of leaves during the 1st year, bolting into an erect plant about 1-2½' tall during the 2nd year. The central stem is 4-angled, winged, and glabrous. Opposite leaves are lanceolate to oval-cordate in shape. The leaves are sessile or slightly clasp the stems. The upper stems terminate in small cymes of flowers. Each flower has a corolla with 5 petals, 5 stamens with yellow anthers, a superior ovary with a divided style, and a green calyx with 5 sepals that are linear-lanceolate. At the center of the flower, the petal bases are yellow to greenish yellow, presenting a small 5-sided star. The blooming period occurs from mid- to late summer.
