DescriptionThis native perennial wildflower is 3-7' tall and largely unbranched, except for the short flowering stalks along the upper one-fourth of its length. The central stem is terete, light green, and either glabrous or canescent. The alternate leaves are 3-8" long and and 2-4" across; they are ovate to broadly ovate and crenate-dentate along their margins. Some leaves may have a pair of lobes that are shallow and broad. The upper leaf surface is yellowish green to medium green and glabrous (or nearly so), while the lower leaf surface is pale green and canescent. The slender petioles are 2-5" long and either light green or reddish green. At the base of each petiole, there is a pair of small linear stipules. The upper flowering stalks are 1½3" long and canescent; each stalk has a single leaf and a single flower. Individual flowers are 4-6" across and a similar length, consisting of 5 white or pink petals, 5 light or yellowish green sepals, a reproductive columnar structure with numerous stamens along its length and 5 styles with knobby stigmata at its apex. The persistent sepals are ovate and canescent (or tomentose); they are united at the base. Each flower usually has a reddish purple throat at the base of its petals, although sometimes this is absent. Directly underneath the sepals, there are about 12 linear bracts that curve upward; they are 1" in length. The blooming period occurs from mid-summer to early fall and lasts about 1 month. Individual flowers are short-lived; usually only 0-2 flowers are in bloom at the same time on a single plant. The flowers are replaced by seed capsules that are about 11¼" long and a little less across; they are globoid-ovoid, short-beaked, and glabrous. Each seed capsule contains a ring of seeds; individual seeds are reniform, flattened, and hairless. This wildflower spreads by reseeding itself.
