Pyrus salicifolia | |
Pyrus salicifolia is a species of pear, native to the Middle East. It is widely grown as an ornamental tree, almost always as a pendulous (or "weeping") cultivar, and is called by various common names, including willow-leaved pear, [2] weeping pear, and similar. The tree is deciduous and of comparatively small stature, rarely reaching 10–12 meters in height. The crown is rounded. It has pendulous, silvery foliage, superficially similar to a weeping willow. The flowers are large and pure white highlighted with black-tipped stamens although the buds are tipped with red. The small green fruits are inedible, being hard and astringent.[ citation needed ]
This tree is cultivated widely in gardens and landscapes. It grows well on infertile sandy soils due to its spreading root system. The trees flower in the spring, but during the rest of the year can be trimmed back and shaped almost like topiary. This species of tree is very susceptible to fireblight, a bacterial pathogen.[ citation needed ]
Pyrus salicifolia may also be confused with Pyrus nivalis which is generally taller and hardly pendulous or with Pyrus elaeagnifolia which has broader entire leaves and longer petioles.[ citation needed ]
The cultivar 'Pendula' has gained the Royal Horticultural Society's Award of Garden Merit. [3] [4]
Pears are fruits produced and consumed around the world, growing on a tree and harvested in late summer into mid-autumn. The pear tree and shrub are a species of genus Pyrus, in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees.
Betula pendula, commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran. It has been introduced into North America, where it is known as the European white birch or weeping birch and is considered invasive in some states in the United States and parts of Canada. The tree can also be found in more temperate regions of Australia.
Salix purpurea, the purple willow, purpleosier willow, or purple osier, is a species of willow native to most of Europe and western Asia north to the British Isles, Poland, and the Baltic States.
Ficus benjamina, commonly known as weeping fig, benjamin fig or ficus tree, and often sold in stores as just ficus, is a species of flowering plant in the family Moraceae, native to Asia and Australia. It is the official tree of Bangkok. The species is also naturalized in the West Indies and in the states of Florida and Arizona in the United States. It is one of the most common trees in Israeli cities and parks. In its native range, its small fruit are favored by some birds.
Pyrus calleryana, or the Callery pear, is a species of pear tree native to China and Vietnam, in the family Rosaceae. It is most commonly known for its cultivar 'Bradford' and its offensive odor, widely planted throughout the United States and increasingly regarded as an invasive species.
Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons.
Pyrus communis, the common pear, is a species of pear native to central and eastern Europe, and western Asia.
Prunus serrulata or Japanese cherry is a species of cherry tree that grows naturally in Japan, China, and Korea, and it also refers to a cultivar produced from Prunus speciosa, a cherry tree endemic in Japan. Historically, the Japanese have developed many cultivars by selective breeding of cherry trees, which are produced by the complicated crossing of several wild species, and they are used for ornamental purposes all over the world. Of these, the cultivars produced by complex interspecific hybrids based on the Oshima cherry are also known as the Cerasus Sato-zakura Group.
Cedrus atlantica, the Atlas cedar, is a species of tree in the pine family Pinaceae, native to the Rif and Atlas Mountains of Morocco, and to the Tell Atlas in Algeria. A majority of the modern sources treat it as a distinct species Cedrus atlantica, but some sources consider it a subspecies of Lebanon cedar.
Salix babylonica is a species of willow native to dry areas of northern China, but cultivated for millennia elsewhere in Asia, being traded along the Silk Road to southwest Asia and Europe.
The hybrid elm cultivar Ulmus × hollandica 'Smithii', commonly known as the Downton Elm, was one of a number of cultivars arising from the crossing of the Wych Elm U. glabra with the Field Elm U. minor. The tree was originally planted at Downton Castle near Ludlow, as one of a batch, not all of them pendulous in habit, raised at Smith's Nursery, Worcester, England, from seeds obtained from a tree in Nottingham in 1810.
Acer japonicum, Fullmoon Maple, Downy Japanese-Maple, is a species of maple native to Japan, on Honshū, Hokkaidō, Kyūshū, and also southern Korea.
Escallonia is a genus of shrubs and trees in the family Escalloniaceae. They are native to North and South America.
The Siberian Elm cultivar Ulmus pumila 'Pendula' is from northern China, where it is known as Lung chao yü shu. It was classified by Frank Meyer in Fengtai in 1908, and introduced to the United States by him from the Peking Botanical Garden as Weeping Chinese Elm. The USDA plant inventory record (1916) noted that it was a "rare variety even in China". It was confirmed as an U. pumila cultivar by Krüssmann (1962).
The elm cultivar Ulmus 'Scampstoniensis', the Scampston Elm or Scampston Weeping Elm, is said to have come from Scampston Hall, Yorkshire, England, before 1810. Loudon opined that a tree of the same name at the Royal Horticultural Society's Garden in 1834, 18 feet (5.5 m) high at 8 years old "differed little from the species". Henry described the tree, from a specimen growing in Victoria Park, Bath, as "a weeping form of U. nitens" [:Ulmus minor ]; however Green considered it "probably a form of Ulmus × hollandica". Writing in 1831, Loudon said that the tree was supposed to have originated in America. U. minor is not, however, an American species, so if the tree was brought from America, it must originally have been taken there from Europe. There was an 'American Plantation' at Scampston, which may be related to this supposition. A number of old specimens of 'Scampstoniensis' in this plantation were blown down in a great gale of October 1881; younger specimens were still present at Scampston in 1911.
Ligustrum ovalifolium, also known as Korean privet, California privet, garden privet, and oval-leaved privet, is a species of flowering plant in the olive family Oleaceae. The species is native to Japan and Korea.
Prunus itosakura, Prunus subhirtella or Edo higan, is the scientific name for one of the wild species of cherry trees native to Japan, and is also the name given to the cultivars derived from this species. Itosakura means thread cherry, and appeared in historical documents from the Heian period in Japan. The scientific name for the hybrid between this species and Prunus incisa is Prunus × subhirtella. Historically, the Japanese have produced many cultivars from this wild species, and they are also called weeping cherry, autumn cherry, or winter-flowering cherry, because of the characteristics of each cultivar.
Weeping trees are trees characterized by soft, limp twigs. This characterization may lead to a bent crown and pendulous branches that can cascade to the ground. While weepyness occurs in nature, most weeping trees are cultivars. Because of their shape, weeping trees are popular in landscaping; generally they need a lot of space and are solitary so that their effect is more pronounced. There are over a hundred different types of weeping trees. Some trees, such as the cherry, have a variety of weeping cultivars. There are currently around 550 weeping cultivars in 75 different genera, although many have now disappeared from cultivation.
Ulmus × hollandica 'Wentworthii Pendula', commonly known as the Wentworth Elm or Wentworth Weeping Elm, is a cultivar with a distinctive weeping habit that appears to have been introduced to cultivation towards the end of the 19th century. The tree is not mentioned in either Elwes and Henry's or Bean's classic works on British trees. The earliest known references are Dutch and German, the first by de Vos in Handboek tot de praktische kennis der voornaamste boomen (1890). At about the same time, the tree was offered for sale by the Späth nursery of Berlin as Ulmus Wentworthi pendulaHort.. The 'Hort.' in Späth's 1890 catalogue, without his customary label "new", confirms that the tree was by then in nurseries as a horticultural elm. De Vos, writing in 1889, states that the Supplement to Volume 1 includes entries announced since the main volume in 1887, putting the date of introduction between 1887 and 1889.
Acer palmatum, commonly known as Japanese maple, palmate maple, or smooth Japanese maple (Korean: danpungnamu, 단풍나무, Japanese: irohamomiji, イロハモミジ, or momiji,, is a species of woody plant native to Korea, Japan, China, eastern Mongolia, and southeast Russia. Many different cultivars of this maple have been selected and they are grown worldwide for their large variety of attractive forms, leaf shapes, and spectacular colors.
