Cosmos parviflorus (Jacq.) Pers.[2] is a plant species in the family Asteraceae. Common names include "Southwestern Cosmos" in the US and "juve" or "aceitilla blanca" in Mexico.[3] In many places it is a common weed in agricultural fields, although it also grows in grassy meadows in forested areas. The species appears to be native in Texas, New Mexico, Colorado, Arizona, and Utah. Collections have also been made from Massachusetts, Maine, Maryland, Missouri, Rhode Island, although it appears to be introduced to those regions.[4] It is also known from many sites in Mexico as far south as Oaxaca.

Description
The plant attains a height of up to 1 m. Leaves are deeply divided into narrow linear segments. Ray flowers red, pink or white, the colors sometimes mixed in the same population. Achenes are barbed, causing them to lodge in fur or clothing. They can thus be transported over long distances.[6][7]
