Exochorda racemosa, the pearlbush or common pearlbush, is a species of plant in the family Rosaceae. This species is mostly found in China and Japan. [3]
Exochorda racemosa was first described by John Lindley. It is placed in the genus Exochorda and family Rosaceae, the rose family. [4] The plant gets its common name, "common pearlbush", from its pearl-looking flowers. [5]
A loose, irregular or vase-shaped and upright shrub, this species is deciduous. It has oblong leaves, about 4–6 cm (1.6–2.4 in) long and 1–2 cm (0.39–0.79 in) wide, that are rounded and toothed at the margin on the top. The flowers are white, and flower in late April to early May. [6] The flowers have round petals, 12-25 stamens, borne in racemes in groups of about six or ten. Their diameter is 4 cm (1.6 in). Flowers give way to brown, dehiscent seed capsules. [2]
Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.
Pinus peuce is a species of pine native to the mountains of Macedonia, Bulgaria, Albania, Montenegro, Kosovo, the extreme southwest of Serbia, and the extreme north of Greece, growing typically at (600-) 1,000-2,200 (-2,300) m altitude. It often reaches the alpine tree line in this area. The mature size is up to 35–40 m height, and 1.5 m trunk diameter. However, the height of the tree diminishes strongly near the upper forest limit and may even obtain shrub sizes.
Magnolia grandiflora, commonly known as the southern magnolia or bull bay, is a tree of the family Magnoliaceae native to the Southeastern United States, from Virginia to central Florida, and west to East Texas. Reaching 27.5 m (90 ft) in height, it is a large, striking evergreen tree, with large, dark-green leaves up to 20 cm long and 12 cm wide, and large, white, fragrant flowers up to 30 cm (12 in) in diameter.
Yucca filamentosa, Adam’s needle and thread, is a species of flowering plant in the family Asparagaceae native to the southeastern United States. Growing to 3 metres tall, it is an evergreen shrub valued in horticulture.
Kerria japonica, commonly known as Japanese kerria or Japanese rose, is a deciduous, yellow-flowering shrub in the rose family (Rosaceae), native to China, Japan and Korea. It is the only species in the genus Kerria. In the wild, it grows in thickets on mountain slopes. Japanese kerria has been used for medicine and is also planted in gardens. A double-flowered cultivar, K. japonica 'Pleniflora', is commonly called bachelor's buttons.
Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is E. racemosa.

Stewartia pseudocamellia, also known as Korean stewartia, Japanese stewartia, or deciduous camellia, is a species of flowering plant in the family Theaceae, native to Japan and Korea.
The winged elm cultivar Ulmus alata 'Lace Parasol' was found by a North Carolina nurseryman growing in local woods. Removed to his yard, it remained there until his death, when it was removed again to the North Carolina State Arboretum in Raleigh by J. C. Raulston.
Buddleja crispa, the Himalayan butterfly bush, is a deciduous shrub native to Afghanistan, Bhutan, North India, Nepal, Pakistan and China, where it grows on dry river beds, slopes with boulders, exposed cliffs, and in thickets, at elevations of 1400–4300 m. Named by Bentham in 1835, B. crispa was introduced to cultivation in 1850, and came to be considered one of the more attractive species within the genus; it ranked 8th out of 57 species and cultivars in a public poll organized by the Center for Applied Nursery Research (CANR) at the University of Georgia, US. In the UK, B. crispa was accorded the Royal Horticultural Society's Award of Merit in 1961. However, the species is not entirely cold-hardy, and thus its popularity is not as ubiquitous as it might otherwise be.
Buddleja utahensis is a species of Buddleja endemic to the southwestern United States, where it is known by the common names Utah butterfly bush and Panamint butterfly bush. Named and described by Coville in 1892, the shrub favours limestone outcrops at elevations of 700–2000 m, where it is often found in association with Joshua trees.
Prunus tomentosa is a species of Prunus native to northern and western China, Korea, Mongolia, and possibly northern India. Common names for Prunus tomentosa include Nanjing cherry, Korean cherry, Manchu cherry, downy cherry, Shanghai cherry, Ando cherry, mountain cherry, Chinese bush cherry, and Chinese dwarf cherry.
Sorbaria sorbifolia, the false spiraea, is a species of flowering plant in the family Rosaceae. The common name is also spelled false spirea. Other common names include false goat's beard, sorb-leaved schizonotus, Ural false spirea, and in Chinese: 珍珠梅; pinyin: zhen zhu mei; lit. 'pearl plum'.
Forsythia × intermedia, or border forsythia, is an ornamental deciduous shrub of garden origin.
Zanthoxylum americanum, the common prickly-ash, common pricklyash, common prickly ash or northern prickly-ash, is an aromatic shrub or small tree native to central and eastern portions of the United States and Canada. It is the northernmost New World species in the citrus family, Rutaceae, and is the type species in its genus, which includes sichuan pepper. It can grow to 10 meters (33 ft) tall with a diameter at breast height (DBH) of 15 cm (5.9 in). It produces membranous leaflets and axillary flower clusters. The wood is not commercially valuable, but oil extracts from the bark have been used in traditional and alternative medicine, and have been studied for antifungal and cytotoxic properties. The genus name is sometimes spelled Xanthoxylum.
Hydrangea stylosa is a species of flowering plant in the family Hydrangeaceae, native to China.
Lonicera nitida is a species of flowering plant in the honeysuckle family. In English, it is sometimes given the common names box honeysuckle or Wilson's honeysuckle. It is widely used as a low hedging plant, and for topiary. It is also a popular low-maintenance ground cover plant for urban landscaping.
Buddleja nivea is a vigorous shrub endemic to western China, evergreen in the wild, but deciduous in cultivation in the UK. The plant was discovered by Wilson in the Yangtze basin at altitudes of 700 – 3,600 m. Introduced to cultivation in 1901, it was named by Duthie in 1905. Several plants similar to the species but originally treated as species and varieties in their own right have now been sunk as B. nivea.
Acer distylum, the lime-leaved maple or linden leaved maple, is a species of flowering plant in the family Sapindaceae, native to north Honshu Island of Japan. Its closest relative is Acer nipponicum, with which it is grouped in the Acer section Parviflora. The species is noted for its 10–15 cm (4–6 in) unlobed leaves, the like of which are not found in any other maple species. The bark is grayish, and has a pink cast in young specimens. Acer distylum was first described by Philipp Franz von Siebold and Joseph Gerhard Zuccarini in 1845, and later brought to Europe by Charles Maries in 1879.
The expanding buds appear as small pearls - hence, the common name.
