Perhaps the second most planted ornamental pear is the Manchurian (Pyrus ussuriensis), also referred to as the Chinese pear. This tree had the misfortune of being confused with the Bradford following a mix up in labeling in Australia that lasted until 1999. Overview. Selected in landscaping for its profusion of fragrant, white flowers, the ornamental pear is part of the Rosaceae family and is an evergreen shrub or tree. These trees are not particular about soil but do require regular watering and full sun. USDA growing zones vary by species. Culture. Ornamental pear trees grow best under full sun. Two cultivars, Redspire and Capital, can take full sun or partial shade. All grow in a wide range of soil types and pH levels, and, though they favor moist soil, will tolerate hot and dry conditions. In addition to its value as an ornamental, the flowering pear tree is useful as a screen, providing your home and yard with both privacy and moderate to dense shade. The ornamental pear and its cultivars, Redspire and Aristocrat are the tallest of the flowering trees, reaching up to 50 feet high. Fauer is the smallest at a diminutive 20 feet tall. The Capital variety is in between, reaching up to 35 feet in height. In recent years, ornamental pear trees have been very popular in Australian gardens. A favourite in cool climate areas is the beautiful Manchurian pear (Pyrus ussuriensis), with its heart-shaped leaves, scented white flowers and spectacular autumn colour. However, the Manchurian pear can grow to around 20m (60′) tall and 10m (30′) wide. These days, available space in backyards is taken up by pools, spas, barbecues, outdoor settings and play areas for the children, so there isn’t much room left for big trees.
