''Caryopteris'' (bluebeard; ) 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).〔(Kew World Checklist of Selected Plant families )〕〔Germplasm Resources Information Network: (''Caryopteris'' )〕〔Flora of China: (''Caryopteris'' )〕〔Flora of Pakistan: (''Caryopteris'' )〕〔Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan ISBN 0-333-47494-5.〕 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.〔〔〔 ;Species〔 #''Caryopteris forrestii'' Diels - Guizhou, Sichuan, Tibet, Yunnan # ''Caryopteris glutinosa'' Rehd. - Sichuan # ''Caryopteris incana'' (Thunb. ex Houtt.)

P.D.Cantino ==Cultivation and uses== Though several ''Caryopteris'' species are grown in botanical gardens, as ornamental plants the species have largely been superseded in gardens by the hybrid ''Caryopteris'' × ''clandonensis'' (''C. incana'' × ''C. mongholica''). The accidental cross that produced it occurred in the garden of Arthur Simmonds at Clandon, near Guildford, Surrey.〔David S. MacKenzie, ''Perennial Ground Covers'', ''s.v.'' "Caryopteris × clandonensis'' 'Arthur Simmonds'".〕 In 1930, wishing to propagate ''C. mongholica'', he gathered seeds from a plant that was growing near ''C. mastacanthus''. When the seedlings eventually flowered in their second year, hybrids appeared. The final selection, however, was made of a self-sown volunteer that appeared under ''C. mastacanthus'', and eventually smothered it. It began winning Royal Horticultural Society medals in 1933.〔Coats (1964) 1992.〕〔"The genus is usually represented by ''Caryopteris × clandonensis'', which has superseded all the original species". Alice M. Coats, ''Garden Shrubs and Their Histories'' (1964) 1992, ''s.v.'' "Caryopteris".〕 This small, deciduous, aromatic shrub has grey-green leaves and produces masses of blue flowers in late summer. There are several cultivars with flowers in shades of blue or white, including 'Blue Mist', 'Heavenly Blue', 'Longwood Blue', 'Dark Knight', 'Summer Sorbet' and 'Pershore'. The cultivars 'Arthur Simmonds',〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=2293 )〕 'First Choice'〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=336 )〕 and 'Worcester Gold'〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=337 )〕 have gained the Royal Horticultural Society's Award of Garden Merit. ''Caryopteris'' × ''clandonensis'', an unusual plant in American gardens in the 1960s,〔Wayside Gardens introduced "blue Mist" in the 1950s: "several years ago" in ''Popular Gardening and Living Outdoors'', 7 (1956:15).〕 has become more familiar there, especially in xeriscaping. Like ''Buddleja'', the woody stems can die back in the winter, particularly in colder climates and on heavy soils. They prefer well-drained, sandy soil in full sun, but does not need especially rich soil or constant moisture. Leaves and herbaceous stems have a terpene aroma like eucalyptus, especially when lightly bruised. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Caryopteris」の詳細全文を読む スポンサード リンク
