Caryopteris (Greek for nut and wing). Verbenaceae. Ornamental woody plants grown for their lavender-blue flowers profusely produced in autumn.

Caryopteris (Greek for nut and wing). Verbenaceae. Ornamental woody plants grown for their lavender-blue flowers profusely produced in autumn.{{SCH}}

Deciduous small shrubs: lvs. opposite, short-petioled, serrate: fls. in axillary cymes; calyx campanulate, deeply 5-lobed with lanceolate teeth, spreading and somewhat enlarged in fr.; corolla 5-lobed, with short cylindric tube and spreading limb, 1 segm. larger and fringed; stamens 4, exserted, 2 of them longer; style slender, 2-parted at the apex: fr. separating into 4 somewhat winged nutlets.—About 6 species in E. Asia.

 

These are glabrous, pubescent or tomentose shrubs with small blue or violet late flowers. Free-flowering and very valuable for their late blooming season; not hardy North; even if well protected they will be killed almost to the ground, but the young shoots, springing up freely, will flower profusely the same season. They require well-drained and sandy soil and sunny position; if grown in pots, a sandy compost of peat and leaf soil or loam will suit them, and they will flower in the greenhouse until midwinter. Propagated readily by cuttings of half-ripened wood in summer or fall under glass, and by seeds sown in spring.

==Cultivation and uses==

==Gallery==

Several ''Caryopteris'' species are grown as [[ornamental plant]]s in gardens. Like ''[[Buddleja]]'', the woody stems can die back in the winter, particularly in colder climates. They prefer well-drained soil in full sun, but does not need especially rich soil or constant moisture.
