Description
Zinnia peruviana is an annual plant up to 50 cm (20 in) tall, rarely 100 cm (39 in) tall.[2][3] The stems are green, but later become yellow or purple.[3] The leaves are ovate, elliptic or lanceolate, 2.5–7 cm long and 8–3.5 cm wide; 3- to 5-nerved.[2][3] The peduncles are 1–7 cm long.[2][3] Flower heads with 6–21 red, maroon or yellow ray florets (with a 0.8–2.5 cm long petal each) surrounding 12–50 yellow disc florets (with 0.1 cm long corolla lobes).[2][3] Fruits (cypselae) oblanceolate to narrowly elliptic, 0.7–1 cm long, 3-angled or compressed, striate.[2][3]
Distribution and habitat
The native range of Z. peruviana spans from southeastern Arizona and the Greater Antilles south to Argentina.[2][3] It grows mostly on open areas or rocky slopes between 800–3,000 m (2,600–9,800 ft) of elevation.[3][4]
It has been introduced to and naturalized in many places such as China, Pakistan, India, Bangladesh, Australia, South Africa and Hawaii.[5][6][7][8][9]
