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.
Witch hazel (Hamamelis) is a genus of flowering shrubs.
Witch-hazels or witch hazels (Hamamelis) are a genus of flowering plants in the family Hamamelidaceae, with three species in North America, and one each in Japan (H. japonica) and China (H. mollis). The North American species are occasionally called winterbloom.
Reed is a common name for several tall, grass-like plants of wetlands.
In biology, trinomial nomenclature is the system of names for taxa below the rank of species. These names have three parts. The usage is different in zoology and botany.
Hazels are plants of the genus Corylus of deciduous trees and large shrubs native to the temperate Northern Hemisphere. The genus is usually placed in the birch family Betulaceae, though some botanists split the hazels into a separate family Corylaceae. The fruit of the hazel is the hazelnut.
Hamamelidaceae, commonly referred to as the witch-hazel family, is a family of flowering plants in the order Saxifragales. The clade consists of shrubs and small trees positioned within the woody clade of the core Saxifragales. An earlier system, the Cronquist system, recognized Hamamelidaceae in the Hamamelidales order.
Custard apple is a common name for several fruits and may refer to Annonaceae, the custard apple family, which includes the following species referred to as custard apples:
Corylus colurna, the Turkish hazel or Turkish filbert, is a deciduous tree native to southeast Europe and southwest Asia, from the Balkans through northern Turkey to northern Iran.
A calcifuge is a plant that does not tolerate alkaline (basic) soil. The word is derived from the Latin 'to flee from chalk'. These plants are also described as ericaceous, as the prototypical calcifuge is the genus Erica (heaths). It is not the presence of carbonate or hydroxide ions per se that these plants cannot tolerate, but the fact that under alkaline conditions, iron becomes less soluble. Consequently, calcifuges grown on alkaline soils often develop the symptoms of iron deficiency, i.e. interveinal chlorosis of new growth. There are many horticultural plants which are calcifuges, most of which require an 'ericaceous' compost with a low pH, composed principally of Sphagnum moss peat. Alternatively sulphur chips may be used to lower soil pH.
Purslane is a common name for several mostly unrelated plants with edible leaves and may refer to:
Corylopsis is a genus of nearly 30 species of shrubs in the witch hazel family, Hamamelidaceae, native to eastern Asia with the majority of species endemic to China but with some also in Japan, Korea, and the Himalayas. This genus is also known from the extinct species Corylopsis reedae described from Eocene leaf fossils found in Washington State, USA.
Wrack is part of the common names of several species of seaweed in the family Fucaceae. It may also refer more generally to any seaweeds or seagrasses that wash up on beaches and may accumulate in the wrack zone.
Walking fern may refer to two species of fern in the genus Asplenium, which are occasionally placed in a separate genus Camptosorus. The name "walking fern" derives from the fact that new plantlets grow wherever the arching leaves of the parent touch the ground, creating a walking effect. Both have evergreen, undivided, slightly leathery leaves that are triangular and taper to a thin point. On the bottom of the leaves, sori, or spore-bearing structures, cluster along the veins. These hardy plants can be found in shady spots of limestone ledges and limy forest places.
Corylopsis reedae is an extinct species of flowering plant in the family Hamamelidaceae known from fossil leaves found in the early Eocene Klondike Mountain Formation deposits of northern Washington state. C. readae is one of the oldest occurrences of the winter-hazel genus Corylopsis, which includes between seven and thirty species, all found in Asia. Fossils from two other occurrences are of similar age to C. readae, with Paleocene specimens from Greenland being placed in the form taxon Corylopsiphyllum and an Eocene Alaskan fossil being included in Corylopsis without species placement.
Corylopsis pauciflora, the buttercup witch hazel or winter hazel, is a species of flowering plant in the family Hamamelidaceae, native to Taiwan and Japan. It is a deciduous, spreading shrub growing to 1.5 m tall by 2.5 m wide. It produces masses of pale yellow flowers in pendent racemes in early spring, followed by leaves opening bronze and turning to rich green. It is cultivated in gardens and parks in temperate regions.
Professor John George Jack was an American dendrologist.
Hemerocallis hakuunensis, known as Baekunsan daylily, is a species in the family Asphodelaceae, native to Korea.
Corylopsis sinensis, the Chinese winter hazel, is a species of flowering plant in the witch-hazel family Hamamelidaceae, native to western China. Growing to 4 m (13 ft) tall and broad, it is a substantial deciduous shrub. With ovate leaves, it produces delicately fragrant, drooping racemes of pale yellow flowers with orange anthers in spring.
