Cota tinctoria

provided by wikipedia EN

Cota tinctoria, the golden marguerite, yellow chamomile, or oxeye chamomile, is a species of perennial flowering plant in the sunflower family. Other common names include dyer's chamomile, Boston daisy, and Paris daisy. In horticulture this plant is still widely referred to by its synonym Anthemis tinctoria.[2]

It is a short-lived plant often treated as biennial, native to Europe, the Mediterranean and Western Asia and naturalized in scattered locations in North America.[3][4] It has aromatic, bright green, feathery foliage. The serrate leaves are bi-pinnatifid (= finely divided) and downy beneath. It grows to a height of 60 cm (24 in).[5]

It has yellow daisy-like terminal flower heads on long thin angular stems, blooming in profusion during the summer.[5]

It has no culinary or commercial uses and only limited medicinal uses. However, it produces excellent yellow, buff and golden-orange dyes, used in the past for fabrics.[6]

Cota tinctoria is grown in gardens for its bright attractive flowers and fine lacy foliage; there is a white-flowering form. Under the synonym Anthemis tinctoria, the cultivar ‘E.C. Buxton’ has gained the Royal Horticultural Society’s Award of Garden Merit.[7] The popular seed-raised cultivar 'Kelwayi' has 5 cm wide, yellow flowers on 65 cm plants.[8]
