Yerevan Botanical Garden
The Yerevan Botanical Garden ( hy, Երևանի բուսաբանական այգի) of the Armenian National Academy of Sciences, is the body responsible for plant collections in Armenia. It is located in the Avan district at the north-eastern part of the capital Yerevan, occupying around 80 hectares of a semi-deserted area. The collection includes more than 200 species of endemic, rare and declining plants, and provides a basis, in a relatively natural environment, for the study of the Armenian flora and the ecological interactions between plant species.J. A. Akopian. ''Conservation of native plant diversity at the Yerevan Botanic Garden, Armenia.'' Kew Bulletin 65, 2010, 663–669. History The Yerevan Botanical Garden was opened in 1935 in the north-eastern part of Yerevan. The Institute of Botany was opened three years later in 1938. The collective greenhouse was founded in 1939 occupying 25 square meters. In 1944 a new greenhouse was built, the overall territory of which was 6 ...

Clematis
''Clematis'' is a genus of about 300 species within the buttercup family, Ranunculaceae. Their garden hybrids have been popular among gardeners, beginning with ''Clematis'' × ''jackmanii'', a garden standby since 1862; more hybrid cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. Most species are known as clematis in English, while some are also known as traveller's joy, a name invented for the sole British native, '' C. vitalba'', by the herbalist John Gerard; virgin's bower for '' C. terniflora'', '' C. virginiana'', and '' C. viticella''; old man's beard, applied to several with prominent seedheads; leather flower for those with fleshy petals; or vase vine for the North American ''Clematis viorna''. Etymology The genus name ''Clematis'' is from Ancient Greek κληματίς : ''clēmatís,'' ("a climbing plant") from κλήμα : ''klḗma'' – 'twig, sprout, tendril'. Over 250 species and cultivars are known, often named for their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aesculus Hippocastanum
''Aesculus hippocastanum'', the horse chestnut, is a species of flowering plant in the maple, soapberry and lychee family Sapindaceae. It is a large, deciduous, synoecious (hermaphroditic-flowered) tree. It is also called horse-chestnut, European horsechestnut, buckeye, and conker tree.

Juniperus Virginiana
''Juniperus virginiana'', also known as red cedar, eastern red cedar, Virginian juniper, eastern juniper, red juniper, and other local names, is a species of juniper native to eastern North America from southeastern Canada to the Gulf of Mexico and east of the Great Plains. Further west it is replaced by the related ''Juniperus scopulorum'' (Rocky Mountain juniper) and to the southwest by ''Juniperus ashei'' (Ashe juniper).Farjon, A. (2005).

Catalpa Bignonioides
''Catalpa bignonioides'' is a species of '' Catalpa'' that is native to the southeastern United States in Alabama, Florida, Georgia, Louisiana, and Mississippi.

The short thick trunk supports long and straggling branches which form a broad and irregular head. The roots are fibrous and branches are brittle, its juices are watery and bitter tasting. The leaves are large, bright green and heart shaped, being long and broad. They appear late, and as they are full-grown before the flower clusters open, they add much to the beauty of the blossoming tree. They secrete nectar, a most unusual characteristic for leaves, by means of groups of tiny glands in the axils of the primary veins. ...

Juglans Nigra
''Juglans nigra'', the eastern American black walnut, is a species of deciduous tree in the walnut family, Juglandaceae, native to North America. It grows mostly in riparian zones, from southern Ontario, west to southeast South Dakota, south to Georgia, northern Florida and southwest to central Texas. Wild trees in the upper Ottawa Valley may be an isolated native population or may have derived from planted trees. Black walnut is an important tree commercially, as the wood is a deep brown color and easily worked. Walnut seeds ( nuts) are cultivated for their distinctive and desirable taste. Walnut trees are grown both for lumber and food, and many cultivars have been developed for improved quality wood or nuts. Black walnut is susceptible to thousand cankers disease, which provoked a decline of walnut trees in some regions. Black walnut is anecdotally known for being allelopathic, which means that it releases chemicals from its roots and other tissues that may harm other organi ...

Liriodendron Tulipifera
''Liriodendron tulipifera''—known as the tulip tree, American tulip tree, tulipwood, tuliptree, tulip poplar, whitewood, fiddletree, and yellow-poplar—is the North American representative of the two-species genus ''Liriodendron'' (the other member is ''Liriodendron chinense''), and the tallest eastern hardwood. It is native to eastern North America from Southern Ontario and possibly southern Quebec to Illinois eastward to southwestern Massachusetts and Rhode Island, and south to central Florida and Louisiana. It can grow to more than in virgin cove forests of the Appalachian Mountains, often with no limbs until it reaches in height, making it a very valuable timber tree. The tallest individual at the present time (2021) is one called the Fork Ridge Tulip Tree at a secret location in the Great Smoky Mountains of North Carolina. Repeated measurements by laser and tape-drop have shown it to be in height. This is the tallest known individual tree in eastern North America. I ...
