Erysimum, or wallflower, is a genus of flowering plants in the cabbage family, Brassicaceae. It includes more than 150 species, both popular garden plants and many wild forms. The genus Cheiranthus is sometimes included here in whole or in part. Erysimum has since the early 21st century been ascribed to a monogeneric cruciferous tribe, Erysimeae, characterised by sessile, stellate (star-shaped) and/or malpighiaceous (two-sided) trichomes, yellow to orange flowers and multiseeded siliques.
Iris is a flowering plant genus of 310 accepted species with showy flowers. As well as being the scientific name, iris is also widely used as a common name for all Iris species, as well as some belonging to other closely related genera. A common name for some species is flags, while the plants of the subgenus Scorpiris are widely known as junos, particularly in horticulture. It is a popular garden flower.
Achillea is a genus of flowering plants in the family Asteraceae, known colloquially as yarrows. The plants typically have frilly leaves. The common name "yarrow" usually refers to A. millefolium. The genus was named after the Greek mythological character Achilles, whose soldiers were said to have used yarrow to treat their wounds; this is reflected by common names such as allheal and bloodwort. The genus is native primarily to Eurasia and North America.
Lonicera periclymenum, common names honeysuckle, common honeysuckle, European honeysuckle, or woodbine, is a species of flowering plant in the family Caprifoliaceae native to much of Europe, North Africa, Turkey and the Caucasus. It is found as far north as southern Norway and Sweden.
Crocosmia (;), also known as montbretia, is a small genus of flowering plants in the iris family, Iridaceae. It is native to the grasslands of southern and eastern Africa, ranging from South Africa to Sudan. One species is endemic to Madagascar.
Hyacinthus orientalis, the common hyacinth, garden hyacinth or Dutch hyacinth, is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae, native to southwestern Asia, southern and central Turkey, northwestern Syria, Lebanon and northern Israel. It was introduced to Europe in the 16th century. It is widely cultivated everywhere in the temperate world for its strongly fragrant flowers which appear exceptionally early in the season, and frequently forced to flower at Christmas time.
Primula vulgaris, the common primrose, is a species of flowering plant in the family Primulaceae, native to western and southern Europe, northwest Africa, and parts of southwest Asia. The common name is primrose, or occasionally common primrose or English primrose to distinguish it from other Primula species also called primroses. None of these are closely related to the evening primroses.
Microbiota is a monotypic genus of evergreen coniferous shrubs in the cypress family Cupressaceae, containing only one species, Microbiota decussata. The plant is native and endemic to a limited area of the Sikhote-Alin mountains in Primorskiy Krai in the Russian Far East. Microbiota is not to be confused with the range of microorganisms of the same name. The genus name was derived from micro-, meaning "small", + Biota, the genus name for a closely related conifer, a species formerly called Biota orientalis, now renamed Platycladus orientalis.
Erica cinerea, the bell heather, is a species of flowering plant in the heath family Ericaceae, native to western and central Europe.
Arabis blepharophylla is a species of flowering plant in the family Brassicaceae, known by the common names coast rock cress and rose rock cress. It is endemic to California, growing mostly in the San Francisco Bay Area and nearby low-elevation California Coast Ranges.
Erysimum cheiri, syn. Cheiranthus cheiri, the wallflower, is a species of flowering plant in the family Brassicaceae (Cruciferae), native to Greece, but widespread as an introduced species elsewhere. It is also treated as a hybrid under the name Erysimum × cheiri. It is widely cultivated as a garden plant.

Orbea variegata is a species of flowering plant in the family Apocynaceae, known as the star flower. It is native to the coastal belt of the Western Cape, South Africa, growing actively during the winter rainfall season. It is an invasive species in southern Australia.
Leucanthemella serotina, called the autumn ox-eye, is a species of flowering plant in the genus Leucanthemella, native to Poland, Czechia, Slovakia, Hungary, Serbia, Croatia, Slovenia, Montenegro, Bosnia and Herzegovina, Macedonia, Romania, Bulgaria, and Ukraine, and introduced to Connecticut, Massachusetts, Michigan, Minnesota and New York in the United States, Ontario and Québec in Canada, and France, Germany, Great Britain, and Switzerland. It is a vigorous, erect perennial growing to 1.5 m (5 ft) tall, bearing flowerheads with white ray florets and greenish-yellow centres, throughout autumn. It has gained the Royal Horticultural Society's Award of Garden Merit, and is also considered by them to be a good plant to attract pollinators.
Erysimum asperum, the western wallflower, is a species of flowering plant in the family Brassicaceae. It is native to west-central Canada, the west-central United States, and northern Mexico; in grasslands generally east of the Continental Divide and west of the Mississippi. It is a member of the Erysimum asperum-E. capitatum species complex.
