A shrub or bush is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead.
Hydrangea, commonly named the hortensia, is a genus of more than 70 species of flowering plants native to Asia and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Korea, and Japan. Most are shrubs 1–3 m tall, but some are small trees, and others lianas reaching up to 30 m (100 ft) by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.
Galls or cecidia are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology.
Salix caprea, known as goat willow, pussy willow or great sallow, is a common species of willow native to Europe and western and central Asia.
Hydrangea macrophylla is a species of flowering plant in the family Hydrangeaceae, native to China. It is a deciduous shrub growing to 2 m (7 ft) tall by 2.5 m (8 ft) broad with large heads of pink or blue flowers in summer and autumn. Common names include bigleaf hydrangea, French hydrangea, lacecap hydrangea, mophead hydrangea, and hortensia. It is widely cultivated in many parts of the world in many climates. It is not to be confused with H. aspera 'Macrophylla'.
Hydrangea quercifolia, commonly known as oakleaf hydrangea or oak-leaved hydrangea, is a species of flowering plant in the family Hydrangeaceae. It is native to the southeastern United States, in woodland habitats from North Carolina west to Tennessee, and south to Florida and Louisiana. A deciduous shrub with white showy flower heads, it is grown as a garden plant, with numerous cultivars available commercially.
Aldridge Gardens is a 30-acre garden, prominently featuring hydrangeas, located on the former Aldridge Estate in Hoover, Alabama, United States.
Climbing hydrangea is a common name for several species in the genus Hydrangea, and also of related species in other genera:
Hydrangea petiolaris, a climbing hydrangea, is a species of flowering plant in the family Hydrangeaceae native to the woodlands of Japan, the Korean peninsula, and on Sakhalin island of easternmost Siberia in the Russian Far East.
Banksia aemula, commonly known as the wallum banksia, is a shrub of the family Proteaceae. Found from Bundaberg south to Sydney on the Australian east coast, it is encountered as a shrub or a tree to 8 m (26 ft) in coastal heath on deep sandy soil, known as Wallum. It has wrinkled orange bark and shiny green serrated leaves, with green-yellow flower spikes, known as inflorescences, appearing in autumn. The flower spikes turn grey as they age and large grey follicles appear. Banksia aemula resprouts from its woody base, known as a lignotuber, after bushfires.
Hydrangea arborescens, commonly known as smooth hydrangea, wild hydrangea, sevenbark, or in some cases, sheep flower, is a species of flowering plant in the family Hydrangeaceae. It is a small- to medium-sized, multi-stemmed, deciduous shrub up to 2 m (7 ft) tall that is native to the eastern United States.
Callicoma is a plant genus that contains just one species, Callicoma serratifolia, a tall shrub or small tree which is native to Australia. Callicoma serratifolia is commonly known as black wattle. One explanation for the name is the similarity of the flowers to those of Australian Acacia, which are commonly known as wattles. Another is its use in wattle and daub huts of the early settlers. The species has a number of other common names include callicoma, butterwood, silver leaf, silver-leaf butterwood and wild quince.
Hydrangea aspera is a species of flowering plant in the family Hydrangeaceae native to dense forests in the region between the Himalayas, across southern China, to Taiwan. It is a large, erect deciduous shrub growing to 3 m (10 ft) tall and wide, with broadly oval leaves and dense branches. The flowers are typically borne in large flat heads in late summer, and are in variable shades of pale blue and pink, fringed by white or pale pink sterile florets.
Photinia serratifolia, commonly called Taiwanese photinia or Chinese photinia is a flowering shrub or tree in the flowering plants family Rosaceae, found in mixed forests of China, Taiwan, Japan, the Philippines, Indonesia, and India.
Wojsławice Arboretum is an arboretum, located in Wojsławice, Dzierżoniów County, Lower Silesian Voivodeship, in south-western Poland. It occupies an area of 62 ha.
Hydrangea serrata is a species of flowering plant in the family Hydrangeaceae, native to mountainous regions of Korea and Japan. Common names include mountain hydrangea and tea of heaven. Growing to 1.2 m (4 ft) tall and broad, it is a deciduous shrub with oval leaves and panicles of blue and pink flowers in summer and autumn (fall). It is widely cultivated as an attractive ornamental shrub throughout the world in areas with suitable climate and soil.
Hydrangea paniculata, or panicled hydrangea, is a species of flowering plant in the family Hydrangeaceae native to southern and eastern China, Korea, Japan and Russia (Sakhalin). It was first formally described by Philipp Franz von Siebold in 1829.
Hydrangea heteromalla is a species of flowering plant in the family Hydrangeaceae. It is commonly known as woolly hydrangea, Himalayan hydrangea or Chinese hydrangea and is native to the Himalayas and China. Average height is 10'-15' with inflorescences that are 5"-8" across and bloom May–June, full flowering only occurs in full sun. Leaves are elliptical or ovate and margins are slightly serrated. Is a very adaptable plant that is hardy to USDA zones (4)5-7. This plant is seldom seen in American gardens. There is a nice specimen at the Sir Harold Hillier Gardens. Hydrangea heteromalla is a deciduous shrub or small tree. Its native habitats include alpine forests and thickets in the Himalayas and China.
Hydrangea hirta, also known as the nettle-leaved hydrangea, is a species of flowering plant in the family Hydrangeaceae that is native to East Asia. Due to the beauty and sturdiness of the species' flowers it can be found outside of its range being used for horticultural and landscaping purposes, and is found in gardens in countries including the United Kingdom and the United States.
Austrobasidium is a genus of fungi in the Exobasidiaceae family. The genus is monotypic and contains the single species Austrobasidium pehueldeni, found parasitizing the woody plant Hydrangea serratifolia in Chile.
