Morris Arboretum
The Morris Arboretum of the University of Pennsylvania (37 ha / 92 acres) is the official arboretum of the Commonwealth of Pennsylvania. The Arboretum is open daily except for major holidays. It is located at 100 East Northwestern Avenue, Chestnut Hill, Philadelphia, Pennsylvania. History The Arboretum was formerly the estate of John T. (1847-1915) and Lydia T. Morris (1849-1932), a brother and sister who purchased and landscaped much of the arboretum's current site beginning in 1887. John Morris was interested in growing plants from around the world, including those collected in China by E. H. Wilson around 1900, and many of today's specimens date to Morris' original plantings. The estate became a public arboretum in 1933, after Lydia Morris' death. ''Note:'' This includes Collection Today the arboretum contains more than 13,000 labelled plants of over 2,500 types, representing the temperate floras of North America, Asia, and Europe, with a primary focus on Asia.

Arboretum
An arboretum (plural: arboreta) in a general sense is a botanical collection composed exclusively of trees of a variety of species. Originally mostly created as a section in a larger garden or park for specimens of mostly non-local species, many modern arboreta are in botanical gardens as living collections of woody plants and is intended at least in part for scientific study. In Latin, an ''arboretum'' is a place planted with trees, not necessarily in this specific sense, and "arboretum" as an English word is first recorded used by John Claudius Loudon in 1833 in ''The Gardener's Magazine'', but the concept was already long-established by then. An arboretum specializing in growing conifers is known as a pinetum. Other specialist arboreta include saliceta (willows), populeta ( poplar), and querceta ( oaks). Related collections include a fruticetum, from the Latin ''frutex'', meaning ''shrub'', much more often a shrubbery, and a viticetum (from the Latin ''vitis,'' meaning vi ...

Platanus × Acerifolia
''Platanus'' × ''acerifolia'', ''Platanus'' × ''hispanica'', or hybrid plane, is a tree in the genus ''Platanus''. It is often known by the synonym London plane, or London planetree. It is usually thought to be a hybrid of ''Platanus orientalis'' (oriental plane) and ''Platanus occidentalis'' (American sycamore). Some authorities think that it may be a cultivar of ''P. orientalis''.

Metasequoia Glyptostroboides
''Metasequoia glyptostroboides'', the dawn redwood, is a fast-growing, endangered deciduous conifer. It is the sole living species of the genus ''Metasequoia'', one of three genera in the subfamily Sequoioideae of the family Cupressaceae. It now survives only in wet lower slopes and montane river and stream valleys in the border region of Hubei and Hunan provinces and Chongqing municipality in south-central China, notably in Lichuan county in Hubei. Although the shortest of the redwoods, it can grow to in height. In 1941, the genus ''Metasequoia'' was reported by paleobotanist Shigeru Miki as a widely distributed extinct genus based on fossils, before attracting considerable attention a few years later when small populations were found alive in central China. It is a particularly well-known example of a living fossil species. The tree faces considerable risks of extinction in its wild range due to deforestation, however it has been planted extensively in arboreta worldwide, whe ...

Fagus Sylvatica
''Fagus sylvatica'', the European beech or common beech is a deciduous tree belonging to the beech family Fagaceae. Description ''Fagus sylvatica'' is a large tree, capable of reaching heights of up to tall and trunk diameter, though more typically tall and up to trunk diameter. A 10-year-old sapling will stand about tall. It has a typical lifespan of 150–200 years, though sometimes up to 300 years. In cultivated forest stands trees are normally harvested at 80–120 years of age. 30 years are needed to attain full maturity (as compared to 40 for Fagus grandifolia, American beech). Like most trees, its form depends on the location: in forest areas, ''F. sylvatica'' grows to over , with branches being high up on the trunk. In open locations, it will become much shorter (typically ) and more massive. The leaves are alternate, simple, and entire or with a slightly crenate margin, long and 3–7 cm broad, with 6–7 veins on each side of the leaf (as opposed to ...
