Zinnia acerosa

provided by wikipedia EN

Zinnia acerosa is a low-growing perennial flowering plant native to the Southwestern United States and Northern Mexico. Common names include desert zinnia, wild zinnia, white zinnia, and spinyleaf zinnia. It is a popular landscape plant in the southwest due to its low water use and long bloom period. The flowers also serve as a food source for southwestern butterflies.

In the United States, Zinnia acerosa grows in Arizona, Utah, New Mexico, and Texas.[2] In Mexico, it has been found in Sonora, Chihuahua, Coahuila, Durango, Nuevo León, Zacatecas, and San Luis Potosí.[3]

Zinnia acerosa is a small, branching subshrub up to 16 cm (6.4 inches) tall. Leaves are very narrow, sometimes needle-shaped, up to 2 cm (0.8 inches) long. The plant produces flower head one per stem, each head with 4-7 yellow or white ray florets surrounding 8-13 yellow or purple disc florets.[3][4]
