Cosmos bipinnatus, commonly called the garden cosmos, Mexican asteror cosmea, is a medium-sized flowering herbaceous plant in the daisy family Asteraceae, native to the Americas. The species and its varieties and cultivars are popular as ornamental plants in temperate climate gardens. Cosmos bipinnatus is an annual that is often considered half-hardy, although plants may reappear via self-sowing for several years. The plant height varies from 0.61–1.83–2.74 m. The cultivated varieties appear in shades of pink and purple as well as white. The branched stem is usually densely to occasionally occupied by fine, split up, rough trichomes, but some specimens are completely hairless. The petiole itself is inconspicuous, winged, 10 (rarely to 15) mm long, and sometimes the leaves are almost sessile. The very conspicuous cup-shaped inflorescences have a diameter of usually 5–7 cm and contain tongue and tubular flowers, which are surrounded by bracts. There are usually 8 outer bracts, and they are ovate to lanceolate-tail-shaped, 7-15 mm long, 3-5 mm wide. The inner bracts are ovate-lanceolate and 8-12 mm long. They are translucent with many black stripes and a clear edge up to 1 mm wide, sometimes with yellowish or pink pigments, the tip is ciliate. The sprout leaves have gold-yellow, thread-like tips and protrude between the tubular flowers. The broadened base of these spreader leaves is translucent, with a yellow line. The mostly eight ray florets are pink to violet or white colored, at the base may show noticeable stains caused by anthocyanin. The tongues are reversely ovate shaped, have a length of usually 20-35 mm and a width of usually 12-20 mm. The tips are almost dull and have three broad, wavy teeth. Below that, they are greatly rejuvenated. In the center of the flower baskets is a large number of tubular flowers (also called disc florets), whose overgrown petals are yellow, turn white in the lower part and reach a length of 5-6 mm. The anthers are brownish-black and about 3 mm long, at the tips are short-triangular, translucent attachments with a length of 0.5-0.8 mm. The branches of the stylus are short and rather dull, with a length of 0.5 mm.
