An 3-5+ ft., upright, hairy perennial with toothed, triangular to heart-shaped leaves and terminal flower clusters. The leaves, toothed and alternate, have long stems, 4-6 inches. Stems are woody and somewhat brittle. The large white (occasionally pinkish) blossoms are 3-4 inches long, with a crimson eye at the center. The petals fold up at night and look as though they had never been open. Stamens extend beyond the flower.
False Cotton is so called because its flower closely resembles the flower of a cotton plant (Gossypium), which is in the same family.
