Dill (Anethum graveolens) is a short-lived perennial herb. It is the sole species of the genus Anethum, though classified by some botanists in a related genus as Peucedanum graveolens (L.) C.B.Clarke. It grows to 40–60 cm (16–24 in) 1 inch, with slender stems and alternate, finely divided, softly delicate leaves 10–20 cm (3.9–7.9 in) long. The ultimate leaf divisions are 1–2 mm (0.039–0.079 in) broad, slightly broader than the similar leaves of fennel, which are threadlike, less than 1 mm (0.039 in) broad, but harder in texture. The flowers are white to yellow, in small umbels 2–9 cm (0.79–3.5 in) diameter. The seeds are 4–5 mm (0.16–0.20 in) long and 1 mm (0.039 in) thick, and straight to slightly curved with a longitudinally ridged 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

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.
