Dodder) is a genus of about 100-170 species of yellow, orange or red (rarely green) parasitic plants. Formerly treated as the only genus in the family Cuscutaceae, recent genetic research by the Angiosperm Phylogeny Group has shown that it is correctly placed in the family Convolvulaceae. The genus is found throughout the temperate to tropical regions of the world, with the greatest species diversity in subtropical and tropical regions; the genus becomes rare in cool temperate climates, with e.g. only four species native to northern Europe.

An illustration of duckweed. Duckweed is an important food source for waterfowl and are eaten by humans in some parts of Southeast Asia (as khai-nam). Some duckweeds are used in freshwater aquariums and ponds where they may spread rapidly, although in a large pond they may be difficult to eradicate once established. The plants can provide nitrate removal (if cropped) and cover for fry. The plants are used as shelter by pond water species, such as bullfrogs and bluegills. The duckweeds are important in the process of bioremediation because they grow rapidly, absorbing excess mineral nutrients, particularly nitrogen and phosphates. A cover of duckweeds will reduce evaporation of water compared to a clear surface.

Lamium album (White Deadnettle) is a flowering plant in the family Lamiaceae, native throughout Europe and western Asia, growing in a variety of habitats from open grassland to woodland, generally on moist, fertile soils. It is a herbaceous perennial plant growing to 50-100 cm tall, with green, four-angled stems. The leaves are 3-8 cm long and 2-5 cm broad, triangular with a rounded base, softly hairy, and with a serrated margin and a petiole up to 5 cm long; they appear superficially similar to those of the Stinging nettle Urtica dioica but do not sting, hence the common name "dead nettle". The flowers are white, produced in whorls ('verticillasters') on the upper part of the stem, the individual flowers 1.5-2.5 cm long

Paeonia) is the only genus in the flowering plant family Paeoniaceae. They are native to Asia, southern Europe and western North America. Most are herbaceous perennial plants 0.5–1.5 metres tall, but some are woody shrubs up to 1.5–3 metres tall. They have compound, deeply lobed leaves, and large, often fragrant flowers, ranging from red to white or yellow, in late spring and early summer. In the past, the peonies were often classified in the family Ranunculaceae, alongside Hellebores and Anemones.

An illustration of: 1, Coralla cut open showing the four stamens; 2, Unripe fruit (lengthwise); 3, ripe capsule split open; and the foxglove plant. Digitalis is a genus of about 20 species of herbaceous perennials, shrubs, and biennials that are commonly called foxgloves. The genus was traditionally placed in the figwort family Scrophulariaceae, but upon review of phylogenetic research, it has now been placed in the much enlarged family Plantaginaceae. The genus is native to Europe, western and central Asia, and northwestern Africa. The scientific name means "finger-like" and refers to the ease with which a flower of Digitalis purpurea can be fitted over a human fingertip. The flowers are produced on a tall spike, are tubular, and vary in colour with species, from purple to pink, white, and yellow. The best-known species is the Common Foxglove, Digitalis purpurea. It is a biennial, often grown as an ornamental plant due to its showy flowers, that range in colour from purples through to whites, with variable marks and spotting. The first year of growth produces only the long, basal leaves. In the second year, the erect leafy stem 0.5-2.5 m tall develops.

Annual Honesty (Lunaria annua) is a tall (height about 1 m), hairy-stemmed biennial plant found throughout Europe, North America, and parts of Asia. It has large, pointed oval leaves with marked serrations. The common name "Honesty" arose in the 16th century, and it may be due to the translucent seed-pods which are like flattened pea-pods and borne on the plant through winter. In South-East Asia and elsewhere, it is called the Money Plant, because its seed pods have the appearance of silver coins. In the United States it may also be known as "Silver Dollars," also because of the seed pods.

Cyperus is a large genus of about 600 species of sedges, distributed throughout all continents in both tropical and temperate regions. They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to 0.5 m deep. The species vary greatly in size, with small species only 5 cm tall, while others can reach 5 m in height. Common names include papyrus sedges, flatsedges, nutsedges, umbrella-sedges and "galingales"

Taraxacum is a large genus of flowering plants in the family Asteraceae. They are native to Europe, North America and Asia and two species, T. officinale and T. erythrospermum, are found as weeds worldwide. The common name Dandelion is given to members of the genus and like other members of the Asteraceae family, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a floret. Many Taraxacum species produce seeds asexually by apomixis, where the seeds are produced without pollination, resulting in offspring that are genetically identical to the parent plant.
