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.

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.

Heartsease (Viola tricolor) is a common European wild flower, growing as an annual or short-lived perennial. It has been introduced into North America, where it has spread widely, and is known as the Johnny Jump Up (though this name is also applied to similar species such as the Yellow Pansy). It is the progenitor of the cultivated Pansy, and is therefore sometimes called Wild Pansy; before the cultivated Pansies were developed, "Pansy" was an alternative name for the wild form.
