Other Uses

The flower heads of this species, plus many other Cosmos, Bidens and Coreopsis species, were major sources of yellow to orange dyes among the pre-Columbian civilizations of Central and South America. In southern Africa, they were adopted as a popular yellow dye by European settlers for domestic textile production and are still used by dyers using natural dyes as a hobby or for textile crafts, to dye wool bright yellow or orange[

]. The flowers should first be boiled for about one hour before adding the mordanted wool to the cooled dye-bath and resuming boiling. Pre-mordanting the fibres with different metallic salts gives various shades of lemon yellow to burnt orange. As a top-dye after a first red dyewood bath (e.g. of Baphia nitida Lodd.), it helps give a scarlet bloom to wool while on indigo-dyed wool, it produces greenish-brown shades[

The flower heads of most Cosmos, Bidens, and Coreopsis species contain flavonoid dyes of the chalcone and aurone groups. The specific flavonoids in Cosmos have not been fully elucidated, though the following have been found: luteolin, a group of flavonols having quercetin as their aglycone, and a group of chalcone glycosides. These are all good yellow colorants[

The flower heads of about two dozen plants are sufficient to dye 0.5 kg of wool or silk. They should be harvested when they open. They are soaked in water and the mixture is cooked until the flower heads become pale. The dye bath is yellowish in an acid solution (e.g. With vinegar) and reddish in a basic solution (e.g. With ammonia or washing soda). Alum and tartaric acid are often added as a mordant. The textile is simmered in the dye bath until the desired depth of colour is achieved, usually after about one hour[
