Harlequin glorybower, also known as stinking chun and paohuatong, is a landscape plant in the genus Clerodendrum, family Verbenaceae. It is native to East China, Central China and Northeast China, and has been introduced at horticultural centers in Beijing, Tianjin, Hebei, Shaanxi, North China and Yanqing. It mostly grows on hillsides, roadsides, stream banks and near villages. It is a deciduous shrub or small tree; young branches have short brown pubescence; leaves are simple and opposite, ovate, 5-16 cm long, apex acuminate, base mostly truncate, margin entire or wavy-toothed, nearly glabrous on both surfaces; petiole 2-8 cm; corymbose cymes borne at the top or in leaf axils; calyx purplish-red, five-lobed almost to the base. The corolla is slender and tubular, five-lobed at the tip, white or pink.

Harlequin glorybower belongs to the family Verbenaceae. It is also called stinking chun. It likes light, tolerates slight shade, prefers moist fertile loam, is fairly drought-tolerant, highly adaptable, has some cold tolerance, dislikes low-lying waterlogged areas, and is quite salt- and alkali-tolerant. It has very few pests and diseases and is easy to manage. It is a deciduous shrub or small tree, up to 8 m tall. Young branches, petioles and inflorescence axes have sparse yellowish-brown soft hairs. Leaves are simple and opposite. Ovate to elliptic, margin entire or slightly wavy-toothed, 5-16 cm long. Corymbose cymes are terminal or axillary, 8-18 cm long; calyx purplish-red, 5-lobed almost to the base; corolla white or tinged with pink, tube slender, 5-lobed at the tip; filaments and anthers both extend beyond the corolla. The nut is nearly spherical, enclosed in the persistent calyx, blue-purple when ripe. The flower shape is unusual and beautiful, the flowering period is long, and the fruit is brightly colored, making it an excellent autumn ornamental tree for flowers and fruit; it is suitable for planting in courtyards, on hillsides, by water, on embankments, on cliffs, in rock crevices and under forest canopies. It occurs in the provinces and regions of North China, East China, Central South China and Southwest China. It is also distributed on the Korean Peninsula, in Japan and in the Philippines.
