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).[1][2][3][4][5]

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.[3][4][5]
