Rostrinucula dependens, commonly known as Weeping Buddleja, is a deciduous shrub native to the slopes and scrublands of North Central and South Central China. It typically grows to a height and width of 3-6 feet (0.9-1.8 meters), featuring a cascading habit with arching branches. The plant is notable for its long, pendulous inflorescences that bear small, tubular flowers, which are a blend of pink and purple hues. These flowers bloom in late summer to fall and are quite showy, attracting butterflies and other pollinators.

Weeping Buddleja is valued for its unique weeping form and the extended flowering period that adds color to gardens when many other plants have finished blooming. It is often used in mixed borders, as a specimen plant, or in butterfly gardens due to its attractiveness to pollinators. This shrub prefers full sun but can tolerate part shade, and it requires well-drained soil with moderate moisture. While generally low-maintenance, it benefits from pruning to maintain its shape and promote vigorous growth. Potential problems include susceptibility to spider mites and root rot if overwatered. It is not known to be invasive outside its native range, but gardeners should always monitor for unexpected spread.CC BY-SA 4.0
