Cosmos parviflorus, commonly known as the southwestern cosmos, is an annual, herbaceous, flowering plant in the Asteraceae family. It is native to parts of the Southwestern United States and most of Mexico (from Chihuahua to Oaxaca) and appears to be introduced in portions of the Northeastern United States (Maryland, Maine, Rhode Island and Massachusetts).
Cosmos parviflorus is an annual, herbaceous, flowering plant that typically grows between 30 to 90 cm (12 to 35 in) tall. The opposite leaves are attached to petioles around 0.5 cm long, and are deeply divided into narrow linear segments. The ray florets are a white, pink or violet colour with the colours sometimes mixed in the same population. The achenes are barbed, causing them to lodge in fur or clothing. They can thus be transported over long distances. [3] [4]
Cosmos parviflorus is native to Mexico (from Chihuahua to Oaxaca) and parts of the United States (Texas, New Mexico, Arizona, Colorado).
