Perhaps most easily distinguished by its three-lobed leaves (to 6" long) which resemble the shape of the 15th-16th century halberd spear. Large, 5-petaled, hollyhock-like flowers (to 6" diameter) with white to pink petals and maroon eyes appear from mid-summer into fall on smooth stout stems rising 4-6' tall. Each flower has a prominent and showy center staminal column. Synonymous with and formerly known as Hibiscus militaris, the specific epithet being in reference to the leaf-shape resemblance to a military weapon.
