Caryopteris

Cladon - Bluebeard ( Caryopteris × clandonensis ' Heavenly Blue ')

The beard Flowers ( Caryopteris ) are a genus of flowering plants in the family Lamiaceae ( Lamiaceae). The hybrid Caryopteris × clandonensis is used in temperate latitudes as an ornamental plant in gardens.

Description and ecology

The beard flower species are deciduous herbaceous plants, subshrubs or shrubs. They grow upright or klimmend. The branches are slender and tube-like. The against-constant leaves are thin and serrated or entire. They often have shiny glands.

In the axils dense, stalked umbels are apparent ( cymes ) of small, blue or lavender flowers. The cup is deformed ( four or ) five ( six) - bidentate or -lobed. The crown has a short tube and is slightly two-lipped. The edge of the petals is wholly or perforated. Of the five Corolla lobe is the lower larger, concave and fringed. The four stamens are attached to the apical part of corolla tube. The ovary has four compartments. The scar is divided into two parts. As pollinators, especially bumblebees and bees come into question, getting to the nectar because of their long suction tubes.

The dry fruits decay mostly into four nutlets.

Systematics and distribution

The genus Caryopteris was erected by Alexander Andreyevich Bunge. Synonyms for Caryopteris Bunge are: Barbula Lour, Mastacanthus Endl. . The genus Caryopteris now belongs to the subfamily Ajugoideae within the family of Lamiaceae and was formerly classified in the family Verbenaceae.

All CaryopterisArten occur in China. One type is located in Mongolia and a variety also occurs in Japan and Korea. The seven species thrive in temperate to subtropical areas.

The genus Caryopteris has previously contain up to 16 species, and since 1999 only seven types:

  • Caryopteris forrestii Diels: it contains two varieties: Caryopteris forrestii Diels var forrestii: It grows at altitudes 1700-3000 meters in the Chinese provinces of Guizhou, Sichuan, Yunnan, and in Xizang.
  • Caryopteris forrestii var minor C.Pei & SLChen ex CYWu: It grows on dry slopes at altitudes of 2000 to 4000 meters in the southwestern Chinese provinces of Sichuan, Yunnan and Northwestern in the southeastern Xizang.
  • Caryopteris incana var angustifolia SLChen & RLGuo: It grows in thickets on rocky sites at altitudes of about 300 meters in the Chinese province of Jiangxi.
  • Caryopteris incana ( Thunb. ex Houtt. ) Miq. var incana: It is distributed in Japan, Korea and the Chinese provinces of Anhui, Fujian, Guangdong, Guangxi, Hubei, Hunan, Jiangsu, Jiangxi, Zhejiang.

Some species that were formerly to the genus Caryopteris are classified since 1999 in other genres, such as:

  • Caryopteris aureoglandulosa ( Vaniot ) CYWu → Schnabelia aureoglandulosa ( Vaniot ) PDCantino
  • Caryopteris bicolor ( Roxb. ex Hardw. ) Mabb. → Pseudocaryopteris bicolor ( Roxb. ex Hardw. ) PDCantino
  • Caryopteris divaricata Maxim. → Tripora divaricata ( Maxim. ) P.D.Cantino
  • Caryopteris nepetifolia ( Benth. ) Maxim. → Schnabelia nepetifolia ( Benth. ) P.D.Cantino
  • Caryopteris paniculata CBClarke → Pseudocaryopteris paniculata ( CBClarke ) PDCantino
  • Caryopteris siccanea W.W.Sm. → Rubiteucris siccanea ( W.W.Sm. ) P.D.Cantino
  • Caryopteris terniflora Maxim. → Schnabelia terniflora ( Maxim. ) P.D.Cantino

Hybrids

The Clandon - Bluebeard ( Caryopteris × clandonensis auct. ) Is a horticulturally created hybrids, which is often grown as an ornamental plant. It is one resulting in the 30s in a nursery in England Caryopteris incana intersection of ( Thunb. ex Houtt. ) Miq. and Caryopteris Bunge mongholica. Some varieties, such as ' Heavenly Blue' with deep blue flowers and ' Kew Blue' with dark green leaves and deep blue flowers that are hardy. The Clandon - beard flower is a woody regularly and loosely branched, small shrub that can reach heights of growth of up to 1 meter and in winter drops its leaves. The opposite, lance-shaped leaves are up to 8 cm long and to 2.5 cm wide. You are at the bottom of the broadest and narrowing upwards and are cut unevenly, for example, entire or they have one to four teeth. The upper leaf surface is dark green, the underside gray-green. All parts of the plant are aromatic scented. The blue flowers are crowded in the inflorescences.
