Pistacia is a genus of flowering plants in the cashew family, Anacardiaceae. It contains 10 to 20 species that are native to Africa and Eurasia from the Canary Islands, all of Africa, and southern Europe, warm and semidesert areas across Asia, and North America from Guatemala to Mexico, as well as southern Texas.
The cowpea is an annual herbaceous legume from the genus Vigna. Its tolerance for sandy soil and low rainfall have made it an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name.
Paulownia tomentosa, common names princess tree, empress tree, or foxglove-tree, is a deciduous hardwood tree in the family Paulowniaceae, native to central and eastern China and the Korean Peninsula. It is an extremely fast-growing tree with seeds that disperse readily and is considered an invasive exotic species in North America that has undergone naturalisation in large areas of the Eastern US, even though it might be able to successfully get established through seeds only under ideal conditions. P. tomentosa has also been introduced to Western and Central Europe, and is establishing itself as a naturalised species there as well.
Wisteria frutescens, commonly known as American wisteria, is a woody, deciduous, perennial climbing vine, one of various wisterias of the family Fabaceae. It is native to the wet forests and stream banks of the southeastern United States, with a range stretching from the states of Virginia to Texas and extending southeast through Florida, also north to Iowa, Michigan, and New York.
Capsicum frutescens is a wild chili pepper having genetic proximity to the cultivated pepper Capsicum chinense native to Central and South America. Pepper cultivars of C. frutescens can be annual or short-lived perennial plants. Flowers are white with a greenish white or greenish yellow corolla, and are either insect- or self-pollinated. The plants' berries typically grow erect; ellipsoid-conical to lanceoloid shaped. They are usually very small and pungent, growing 10–20 millimetres (0.39–0.79 in) long and 3–7 millimetres (0.12–0.28 in) in diameter. Fruit typically grows a pale yellow and matures to a bright red, but can also be other colors. C. frutescens has a smaller variety of shapes compared to other Capsicum species. C. frutescens has been bred to produce ornamental strains because of its large quantities of erect peppers growing in colorful ripening patterns.
Vachellia farnesiana, also known as Acacia farnesiana, and previously Mimosa farnesiana, commonly known as sweet acacia, huisache, casha tree, or needle bush, is a species of shrub or small tree in the legume family, Fabaceae. Its flowers are used in the perfume industry.
Asclepias incarnata, the swamp milkweed, rose milkweed, rose milkflower, swamp silkweed, or white Indian hemp, is a herbaceous perennial plant species native to North America. It grows in damp through wet soils and also is cultivated as a garden plant for its flowers, which attract butterflies and other pollinators with nectar. Like most other milkweeds, it has latex containing toxic chemicals, a characteristic that repels insects and other herbivorous animals.
Sanguisorba minor, the salad burnet, garden burnet, small burnet, burnet, pimpernelle, Toper's plant, and burnet-bloodwort, is an edible perennial herbaceous plant in the family Rosaceae. It has ferny, toothed-leaf foliage; the unusual crimson, spherical flower clusters rise well above the leaves on thin stems. It generally grows to 25–55 cm tall. The large, long, taproots store water, making it drought-tolerant.
Leucophyllum is a genus of evergreen shrubs in the figwort family, Scrophulariaceae, native to the southwestern United States and Mexico. It is sometimes placed in the family Myoporaceae. The dozen-odd species are often called "sages", although they have no relationship to the genus Salvia.
Ulmus alata, the winged elm or wahoo, is a small- to medium-sized deciduous tree endemic to the woodlands of the southeastern and south-central United States. The species is tolerant of a wide range of soils, and of ponding, but is the least shade-tolerant of the North American elms. Its growth rate is often very slow, the trunk increasing in diameter by less than 5 mm per year. The tree is occasionally considered a nuisance as it readily invades old fields, forest clearings, and rangelands, proving particularly difficult to eradicate with herbicides.
Ulmus serotina, the September elm, is an autumn-flowering North American species of tree. It is uncommon beyond Tennessee; it is only very locally distributed through Illinois, Kentucky, Arkansas, Mississippi, Oklahoma, Alabama, and Georgia, and disjunct populations into Nuevo León, Mexico. It grows predominantly on limestone bluffs and along streams to elevations of 400 m.
Tecoma stans is a species of flowering perennial shrub in the trumpet vine family, Bignoniaceae, that is native to the Americas. Common names include yellow trumpetbush, yellow bells, yellow elder, ginger Thomas. Tecoma stans is the official flower of the United States Virgin Islands and the floral emblem of The Bahamas.
Leucophyllum frutescens is an evergreen shrub in the figwort family, Scrophulariaceae, native to the U.S. state of Texas, where it is the official "State Native Shrub of Texas", and to the states of Coahuila, Nuevo León, and Tamaulipas in northern Mexico. Although commonly known as Texas sage, it is not a true sage and is distinct from the genus Salvia. The species is also called Texas Ranger, Texas rain sage, cenizo, Texas silverleaf, Texas barometerbush, ash-bush, wild lilac, purple sage, senisa, cenicilla, palo cenizo, or hierba del cenizo.
Verbena bonariensis, the purpletop vervain, clustertop vervain, Argentinian vervain, tall verbena or pretty verbena, is a member of the verbena family cultivated as a flowering annual or herbaceous perennial plant. In United States horticulture, it is also known by the ambiguous names purpletop and South American vervain. For the misapplication "Brazilian verbena" see below.
Alhagi maurorum is a species of legume commonly known, variously, as camelthorn, Caspian manna, and Persian mannaplant. This shrub is native to the region extending from the Mediterranean to Russia, but has been introduced to many other areas of the world, including Australia, southern Africa, and the western United States. The perennial plant grows from a massive rhizome system which may extend over six feet into the ground. New shoots can appear over 20 feet from the parent plant. Above the ground, the plant rarely reaches four feet in height. It is a heavily branched, gray-green thicket with long spines along the branches. It bears small, bright pink to maroon pea flowers and small legume pods, which are brown or reddish and constricted between the seeds. The seeds are mottled brown beans.
Mesembryanthemum crystallinum is a species of annual/perennial, succulent flowering plant in the "mesemb" genus of the Aizoaceae family.
Argyranthemum frutescens, known as Paris daisy, marguerite or marguerite daisy, is a perennial plant known for its flowers. It is native to the Canary Islands. Hybrids derived from this species are widely cultivated as ornamental plants in private gardens and public parks in many countries, and have naturalized in Italy and southern California. There are many cultivars, but the most common has white petals.
Iva frutescens is a species of flowering plant in the family Asteraceae known by the common names Jesuit's bark, bigleaf marsh-elder, and high-tide bush. It grows in coastal eastern North America from Nova Scotia down the eastern coast and along the Gulf Coast to Texas.
Terminalia sericea is a species of deciduous tree of the genus Terminalia that is native to southern Africa. Its common names include clusterleaf, silver cluster-leaf or silver terminalia in English, vaalboom in Afrikaans and mususu in Venda.
Bocconia frutescens is a species of flowering plant in the poppy family known by many common names, including plume poppy, tree poppy, tree celandine, parrotweed, sea oxeye daisy, and John Crow bush in English, gordolobo, llorasangre, tabaquillo, palo amarillo, palo de toro and pan cimarrón in Spanish, bois codine in French and bwa kodenn in Haitian Kreyòl. It is native to the Americas, including Mexico, parts of Central and South America, and the West Indies. It is perhaps better known in Hawaii, where it is an introduced species and an aggressive invasive weed with rapid negative effects on local ecosystems. In other parts of the United States it is used as an ornamental plant for its "tropical"-looking foliage.
