Tropaeolum, commonly known as nasturtium, is a genus of roughly 80 species of annual and perennial herbaceous flowering plants. It was named by Carl Linnaeus in his book Species Plantarum, and is the only genus in the family Tropaeolaceae.

The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity.
Eulophia, commonly known as corduroy orchids, is a genus of about two hundred species of flowering plants in the orchid family, Orchidaceae. Most Eulophia orchids are terrestrial but some are deciduous while others are evergreen. They either have an underground rhizome or pseudobulbs on the surface and those species with leaves have them on the end of a fleshy stem. The flowers are arranged on a thin flowering spike, the flowers having sepals which are larger than the petals. The genus is widely distributed but most species are found in Africa and Asia, usually growing in shady places with grass or shrubs in forests.
Pelargonium is a genus of flowering plants that includes about 280 species of perennials, succulents, and shrubs, commonly called geraniums, pelargoniums, or storksbills. Geranium is also the botanical name and common name of a separate genus of related plants, also known as cranesbills. Both genera belong to the family Geraniaceae, and Carl Linnaeus originally included all the species in one genus, Geranium; they were later separated into two genera by Charles Louis L'Héritier de Brutelle in 1789.
Coleus amboinicus, synonym Plectranthus amboinicus, is a semi-succulent perennial plant in the family Lamiaceae with a pungent oregano-like flavor and odor. Coleus amboinicus is considered to be native to parts of Africa, the Arabian Peninsula, and India, although it is widely cultivated and naturalized elsewhere in the tropics where it is used as a spice and ornamental plant. Common names in English include Indian borage, country borage, French thyme, Indian mint, Mexican mint, Cuban oregano, broad leaf thyme, soup mint, Spanish thyme. The species epithet, amboinicus refers to Ambon Island, in Indonesia, where it was apparently encountered and described by João de Loureiro (1717–1791).
Rudbeckia hirta, commonly called black-eyed Susan, is a North American flowering plant in the family Asteraceae, native to Eastern and Central North America and naturalized in the Western part of the continent as well as in China. It has now been found in all 10 Canadian Provinces and all 48 of the states in the contiguous United States.
Strelitzia reginae, commonly known as the crane flower, bird of paradise, or isigude in Nguni, is a species of flowering plant native to the Cape Provinces and KwaZulu-Natal in South Africa. An evergreen perennial, it is widely cultivated for its dramatic flowers. In temperate areas it is a popular houseplant.
Heliotropium arborescens, the garden heliotrope or just heliotrope, is a species of flowering plant in the borage family Boraginaceae, native to Bolivia, Colombia, and Peru. Common names also include cherry pie and common heliotrope. It is an economically damaging invasive species in Australia.
Plectranthus is a genus of about 85 species of flowering plants from the sage family, Lamiaceae, found mostly in southern and tropical Africa and Madagascar. Common names include spur-flower. Plectranthus species are herbaceous perennial plants, rarely annuals or soft-wooded shrubs, sometimes succulent; sometimes with a tuberous base.
Mertensia virginica is a spring ephemeral plant in the Boraginaceae (borage) family with bell-shaped sky-blue flowers, native to eastern North America.
Tropaeolum majus, the garden nasturtium, nasturtium, Indian cress or monk's cress, is a species of flowering plant in the family Tropaeolaceae, originating in the Andes from Bolivia north to Colombia. An easily-grown annual or short-lived perennial with disc-shaped leaves and brilliant yellow, orange or red flowers, it is of cultivated, probably hybrid origin. It is not closely related to the genus Nasturtium.
Coleus argentatus, synonym Plectranthus argentatus, common name silver spurflower, is a species of flowering plant in the mint family. It is native to rock outcrops and rainforest in the border region of Queensland and New South Wales, Australia. Growing to 1 m (3 ft) tall and broad, it is a spreading deciduous shrub. The hairy leaves are ovate to broad-ovate, 5–11.5 cm long, 3–5.5 cm wide with crenate margins. The hairs give the plant an overall sage green to silvery colour. The flowers are borne on terminal racemes up to 30 cm (12 in) long, and are bluish white.
Coleus scutellarioides, commonly known as coleus, is a species of flowering plant in the family Lamiaceae, native to southeast Asia through to Australia. Typically growing to 60–75 cm (24–30 in) tall and wide, it is a bushy, woody-based evergreen perennial, widely grown for the highly decorative variegated leaves found in cultivated varieties. Another common name is painted nettle, reflecting its relationship to deadnettles, which are in the same family. The synonyms Coleus blumei, Plectranthus scutellarioides and Solenostemon scutellarioides are also widely used for this species.
Ornithogalum nutans, known as drooping star-of-Bethlehem, is a species of flowering plant in the family Asparagaceae, native to Europe and South West Asia. It is a bulbous perennial growing to 20–60 cm (8–24 in) tall by 5 cm (2 in) wide, with strap-shaped leaves and green striped, pendent grey-white flowers in spring. It is cultivated, and has naturalized, outside its native range, for example in North America. It has become extremely invasive along the Chesapeake and Ohio Canal in Maryland. At least in North America, it is not as common as Ornithogalum umbellatum.
Plectranthus fruticosus, the forest spurflower, is a species of flowering plant in the mint family, Lamiaceae. It is native to Mozambique, Eswatini, and South Africa's KwaZulu-Natal, Northern, and Cape provinces. Growing up to 2 m (6.6 ft) tall, it is an erect evergreen shrub, with rounded, hairy leaves, and spikes of soft blue or mauve flowers in summer.
Plectranthus oertendahlii is a species of flowering plant in the sage and mint family, Lamiaceae. Common names include silverleaf spurflower, Swedish ivy, Oertendahl's spurflower, November lights and Brazilian coleus, though it is native to eastern South Africa rather than Brazil. Plectranthus oertendahlii and the cultivar 'Uvongo' have gained the Royal Horticultural Society's Award of Garden Merit.
Coleus madagascariensis, synonym Plectranthus madagascariensis, called thicket coleus, Madagascar coleus and candle plant, is a species of flowering plant in the family Lamiaceae. It is native to South Africa, Eswatini, Mozambique, Mauritius and Réunion, but not Madagascar. Its cultivar 'Variegated Mintleaf' has gained the Royal Horticultural Society's Award of Garden Merit.
Plectranthus ambiguus, the pincushion spurflower, is a species of flowering plant in the family Lamiaceae, native to the Eastern Cape and Kwazulu-Natal provinces of South Africa.

Plectranthus purpuratus or cliff spurflower is a species of flowering plant in the family Lamiaceae, native to South Africa's Kwazulu-Natal and Mpumalanga provinces, as well as eSwatini. The name is frequently misapplied to Plectranthus ciliatus, presumably because both have purple-backed leaves.
