Honeysuckles are arching shrubs or twining vines in the genus Lonicera of the family Caprifoliaceae, native to northern latitudes in North America and Eurasia. Approximately 180 species of honeysuckle have been identified in both continents. Widely known species include Lonicera periclymenum, Lonicera japonica and Lonicera sempervirens. L. japonica is a highly invasive species considered a significant pest in parts of North America, Europe, South America, Australia, and Africa.
Lonicera morrowii, the Morrow's honeysuckle, is a deciduous honeysuckle in the family Caprifoliaceae, native to Japan, Korea, and Northeast China. It is a shrub, reaching a height of 2–2.5 m, with oblong leaves 4–6 cm long. It leafs out quite early in the spring, and in North America is commonly the first deciduous shrub with foliage in March. The flowers are white to pale yellow, and the fruit is a dark red berry 7–8 mm diameter containing numerous seeds. The berries, while eaten frequently by birds, are considered poisonous to humans. It is colloquially called "bush honeysuckle" in the United States, and is considered an invasive species.
In chemistry, a glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. Several species of Heliconius butterfly are capable of incorporating these plant compounds as a form of chemical defense against predators. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body.
Saponins, also selectively referred to as triterpene glycosides, are bitter-tasting usually toxic plant-derived organic chemicals that have a foamy quality when agitated in water. They are widely distributed but found particularly in soapwort, a flowering plant, the soapbark tree and soybeans. They are used in soaps, medicines, fire extinguishers, speciously as dietary supplements, for synthesis of steroids, and in carbonated beverages. Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin and quillaia, a bark extract used in beverages.
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'.
Lilium speciosum is an East Asian species of plants in the lily family. It is native to southern Japan and southern China, where it can be found at elevations of 600–900 metres (2,000–3,000 ft). It is sometimes called the Japanese lily though there are other species with this common name.
Lonicera caerulea, also known by its common names blue honeysuckle, sweetberry honeysuckle, fly honeysuckle, blue-berried honeysuckle, or the honeyberry, is a non-climbing honeysuckle native throughout the cool temperate Northern Hemisphere regions of North America, Europe, and Asia.
Lonicera maackii, the Amur honeysuckle, is a species of honeysuckle in the family Caprifoliaceae that is native to temperate eastern Asia; specifically in northern and western China south to Yunnan, Mongolia, Primorsky Krai in southeastern Siberia, Korea, and, albeit rare there, central and northern Honshū, Japan.
Polygonatum odoratum, the angular Solomon's seal or scented Solomon's seal, is a species of flowering plant in the family Asparagaceae, native to Europe, the Caucasus, Siberia, the Russian Far East, China, Mongolia, Korea, Nepal and Japan. In the United Kingdom it is one of three native species of the genus, the others being P. multiflorum and P. verticillatum.
Lonicera sempervirens is a flowering plant species of honeysuckle vine native to the eastern United States which is known for its reddish flowers.
Centaurium erythraea is a species of flowering plant in the gentian family known by the common names common centaury and European centaury.
Cornus officinalis, the Japanese cornel or Japanese cornelian cherry, is a species of flowering plant in the dogwood family Cornaceae. Despite its name, it is native to China and Korea as well as Japan. It is not to be confused with C. mas, which is also known as the Cornelian cherry. It is not closely related to the true cherries of the genus Prunus.
Aucubin is an iridoid glycoside. Iridoids are commonly found in plants and function as defensive compounds. Iridoids decrease the growth rates of many generalist herbivores.
Etlingera fulgens is a species of herbaceous perennial plant of the family Zingiberaceae. This species occurs in southern Thailand and peninsular Malaysia. E. fulgens is used as an ornamental plant in landscape gardens for its bright red flowers and young leaves.
Bobgunnia madagascariensis, also called the snake bean plant, is a species of legume in the family Fabaceae. Sometimes sold as "Pau Rosa", along with Bobgunnia fistuloides.
Clerodendrum infortunatum, known as bhat or hill glory bower, is a perennial shrub belonging to the family Lamiaceae, also sometimes classified under Verbenaceae. It is the type species among ~150 species of Clerodendrum. It is one of the most well-known natural health remedies in traditional practices and siddha medicine.
Toxicodendron succedaneum, the wax tree, Japanese Hazenoki tree, sơn in Vietnamese or charão in Portuguese, is a flowering plant species in the genus Toxicodendron found in Asia, although it has been planted elsewhere, most notably Australia and New Zealand. It is a large shrub or tree, up to 8 m tall, somewhat similar to a sumac tree. Because of its beautiful autumn foliage, it has been planted outside Asia as an ornamental plant, often by gardeners who were apparently unaware of the dangers of allergic reactions. It is now officially classified as a noxious weed in Australia and New Zealand. It is one of the city tree symbols of Kurume, Fukuoka, Japan.
Trachelospermum asiaticum, the Asiatic jasmine, is a species of flowering plant in the family Apocynaceae and it is native to Asia. Its flowers resemble stars, so it is also referred to as yellow star jasmine or Asian star jasmine. This is a fast growing evergreen vine, often used to cover fences, walls, and similar surfaces. It is heat- and cold- tolerant, and grows even in shady areas.
Phlomoides tuberosa, the sage-leaf mullein, is a perennial herbaceous flowering plant in the family Lamiaceae, native to China, Kazakhstan, Kyrgyzstan, Mongolia, Russia; SW Asia and Europe. Enlarged, tuberous roots give rise to erect stems to 150 cm bearing purple-red flowers.
Lonicera similis is a species of flowering plant in the family Caprifoliaceae, native to Western China. This honeysuckle is known in cultivation by the variety delavayi which is reported by some authorities to be synonymous with L. similis itself. It is a large, twining, semi-evergreen shrub growing to 8 m (26 ft) tall by 1.5 m (4.9 ft) broad, with a profusion of fragrant tubular flowers opening white and ageing to yellow, in late summer and autumn. The flowers are followed by black berries. The Latin specific epithet similis means “similar to”. It is similar in appearance to L. japonica, but larger and more robust. The name delavayi honours the French missionary and botanist Père Jean Marie Delavay (1834-1895).
