Cosmos Bipinnatus

Cosmos bipinnatus, commonly called the garden cosmos or Mexican aster, 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 2-6 ft to (rarely) 9 ft (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, some specimens are completely hairless. The petiole itself is inconspicuous, winged, 10 (rarely to 15) mm (25⁄64–19⁄32 in) long, sometimes the leaves are almost sessile.

The partial leaves are linear-filiform to narrow linear with a width of 0.5 to 1 (rarely to 1.7) mm (3⁄128–5⁄128–9⁄128 in); the tips are pointed, hardened, but not particularly sharp. Its foliage is finely cut into threadlike segments. When flowering, the plant can become top heavy. This problem is alleviated when grown in groups, as the bipinnate leaves interlock, and the colony supports itself.

The achenes become blackish, are smooth or short-bristly. Their shape is spindle-like. They are rounded off into a short, 0.5 to 1.7 millimetres (3⁄128 to 9⁄128 in) long, but distinctly pronounced rostrum. The inner achenes are up to 18 millimetres (91⁄128 in) long, their yellowish beaks are 4 to 5 (rarely to 10) mm (5⁄32–25⁄128–25⁄64 in) long. A pappus is missing or it consists only of two to three awn-like, 1 to 3 millimetres (5⁄128 to 15⁄128 in) large bristles.
