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

Deciduous small shrubs: leaves opposite, short-petioled, serrate: flowers in axillary cymes; calyx campanulate, deeply 5-lobed with lanceolate teeth, spreading and somewhat enlarged in fruit; corolla 5-lobed, with short cylindric tube and spreading limb, 1 segment larger and fringed; stamens 4, exserted, 2 of them longer; style slender, 2-parted at the apex: fruit 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.
