Caryopteris

Caryopteris (bluebeard; Chinese: 莸属 you shu) is a genus of flowering plants in the family Lamiaceae (formerly often placed in the family Verbenaceae). They are native to east Asia (China, Korea, Japan, Mongolia).

They are herbaceous plants or small shrubs growing to 1–4 m tall. The leaves are opposite, simple ovate to lanceolate, with an entire or crenate margin; they are often aromatic. The blue or white flowers are pollinated by butterflies and bumblebees. The fruit is a four-valved capsule containing four seeds.
