Prunus avium, commonly called wild cherry, sweet cherry or gean, is a species of cherry, a flowering plant in the rose family, Rosaceae. It is native to western Eurasia and naturalized elsewhere. It is an ancestor of P. cerasus (sour cherry). All parts of the plant except for the ripe fruit are slightly toxic, containing cyanogenic glycosides. The species is often cultivated as an ornamental tree.

Orchis mascula, the early-purple orchid, early spring orchis, is a species of flowering plant in the orchid family, Orchidaceae.

Symphoricarpos is a small genus of about 15 species of deciduous shrubs in the family Caprifoliaceae. With the exception of the Chinese coralberry, S. sinensis, which is indigenous to western China, all species are native to North and Central America. The name of the genus is derived from the Ancient Greek words συμφορεῖν (sumphoreîn), meaning "to bear together", and καρπός (karpós), meaning "fruit". It refers to the closely packed clusters of berries the species produces. Species in the genus are known by several common names, including snowberry, waxberry and ghostberry. Snowberry is a

The damson, damson plum, or damascene (Prunus domestica subsp. insititia, sometimes Prunus insititia), is an edible drupaceous fruit, a subspecies of the plum tree. Varieties of insititia are found across Europe, but the name damson is derived from and most commonly applied to forms that are native to Great Britain. Damsons are small, ovoid, plum-like fruit with a distinctive, somewhat astringent taste, and are widely used for culinary purposes, particularly in fruit preserves and jams. In South and Southeast Asia, the term damson plum sometimes refers to jamblang, the fruit from a tree in

Alhagi is a genus of Old World plants in the family Fabaceae. They are commonly called camelthorns or manna trees. There are four accepted species, which range from northern Africa and Greece through western and central Asia to India and northern China. Alhagi species have proportionally the deepest root system of any plants - a 1 m (3 ft 3 in) high shrub may have a main root more than 15 m (49 ft) long; due to their deep root system Alhagi species are drought-avoiding plants that utilize ground water, adapting in that way perfectly to the hyper-arid environment. Alhagi species are used as

Myristica is a genus of trees in the family Myristicaceae. There are over 150 species, distributed in Asia and the western Pacific as far as Vanuatu. The type species of the genus, and the most economically important member, is Myristica fragrans (the nutmeg tree), from which mace is also derived.

Corallorhiza, the coralroot, is a genus of flowering plants in the orchid family. Except for the circumboreal C. trifida, the genus is restricted to North America (including Mexico, Central America and the West Indies). Most species are putatively parasitic, relying entirely upon mycorrhizal fungi within their coral-shaped rhizomes for sustenance. Because of this dependence on myco-heterotrophy, they have never been successfully cultivated. Most species are leafless and rootless. Most species produce little or no chlorophyll, and do not utilize photosynthesis. An exception is the yellowish

Geranium dissectum or cut-leaved crane's-bill is a plant species of the genus Geranium. It is native to Europe. It can be found on other continents as well, in some instances as an introduced species. It can be found in North America, where it is known as the cutleaf geranium. Extracts of Geranium dissectum are reported to improve germination rates of Hemp seeds.

Carex paniculata, the greater tussock-sedge, is a species of flowering plant in the sedge family, Cyperaceae. It grows 1.5 metres (4 ft 11 in) high and can be found in most of Europe (including Britain), Northwest Asia and North America.

Trifolium alexandrinum (Egyptian clover, berseem clover) is a species of clover. The plant can reach 75 cm (30 in) tall, with trifoliate leaves and whitish flowers. It is native to northeast Africa and southwest Asia.

Ocimum americanum, known as American basil, lime basil, or hoary basil, is a species of annual herb in the family Lamiaceae. Despite the misleading name, it is native to Africa, the Indian subcontinent, China, and Southeast Asia. The species is naturalized in Queensland, Christmas Island, and parts of tropical America.

Hypericum montanum is a plant species in the genus Hypericum commonly known as pale St. John's-wort or mountain St. John's wort. It is native to Eurasia and Morocco in North Africa.

Elymus caninus, the bearded couch or bearded wheatgrass, is a species of flowering plant in the family Poaceae that is native to Europe including the UK but can be found introduced in the US states of Oregon and Washington. E. caninus has been observed in two morphotypes; the first population being "pauciflorum," with the second being "caninus." Found in the forest regions throughout Europe and stretching as far as west Asia, Elymus caninus is a type of self-pollinating wheatgrass. It is described as green, lax-leafed, and caespitose. The widespread distribution of E. caninus has led to

Carex brizoides, the quaking sedge or quaking-grass sedge, is a species in the genus Carex, native to central and southern Europe. Even where it is a native species, in disturbed woodlands it tends to behave invasively, forming a thick layer on the forest floor and reducing species diversity.

Veronica montana or wood speedwell is a perennial species of flowering plant from the genus Veronica. It also belongs to the family Plantaginaceae.

Sisymbrium loeselii is a species of flowering plant in the family Brassicaceae known by several common names, including small tumbleweed mustard, false London-rocket, and tall hedge mustard. It is native to Eurasia, and it is known on other continents as an introduced species and in some areas a common roadside weed. It is an annual herb producing a hairy, erect stem which can exceed a meter in height. The leaf blades are divided into triangular, lance-shaped, and toothed linear lobes, and are borne on petioles. The top of the stem is occupied by a raceme of flowers with bright yellow petals

Callitriche hermaphroditica (vernacular name: autumnal water-starwort) is a species of flowering plant belonging to the family Plantaginaceae. Its native range is Subarctic and Temperate Northern Hemisphere.

After its former genus Sprekelia has been merged into the genus Zephyranthes in 2019, it was formally transferred to Zephyranthes in 2024.

Sedum hispanicum, the Spanish stonecrop, is a species of flowering plant in the family Crassulaceae.

Salix aegyptiaca, known as the Persian willow, is a large shrub or small tree from the genus of willow (Salix) with red branches that are tomentose in the first two years and leaves up to 15 centimeters long.

Solanum pimpinellifolium, commonly known as the currant tomato or pimp, is a wild species of tomato native to Ecuador and Peru but naturalized elsewhere, such as the Galápagos Islands. Its small fruits are edible, and it is commonly grown in gardens as an heirloom tomato, although it is considered to be wild rather than domesticated as is the commonly cultivated tomato species Solanum lycopersicum. Its genome was sequenced in 2012.
