DescriptionThis native perennial wildflower is 12½' tall and unbranched. The erect central stem is pale green, terete, and covered with short pubescence. The opposite leaves are up to 3" long and ¾" across; they are linear-lanceolate or lanceolate-oblong, pale green, and smooth to slightly dentate along their margins (if teeth are present, they are small and widely spaced). Both the lower and upper surfaces of the leaves are short-pubescent. The central stem terminates in a panicle of flowers that is taller than it is wide. Individual flowers are about ¾" long, consisting of a white tubular corolla and a short pale green calyx with 5 teeth. The corolla becomes gradually wider, forming an upper lip with 2 lobes and a lower lip with 3 lobes. The lower lip projects outward to a greater extent than the upper lip. Along the bottom of the corolla's interior, there are 3 faint purple veins and a pair of low ridges. Toward the throat of the corolla, there is an elongated patch of yellow hairs. The exterior of the corolla is slightly pubescent. The pedicels and calyces of the flowers are also pubescent. The blooming period occurs from mid-spring to early summer and lasts about 3 weeks. There is no noticeable floral scent. Each flower is replaced by a seed capsule containing several small seeds. This wildflower reproduces by reseeding itself.
