Zinnia angustifolia, the narrowleaf zinnia,[2] is a herbaceous flowering plant species of zinnia native to northern and western Mexico and naturalized in parts of the Southwestern United States. Hybrids between Z. angustifolia and other species of Zinna are popular garden plants.[3]

Description[edit]

Zinnia angustifolia is an annual or perennial[4] growing up to 50 cm (20 inches) tall. The stems have many branches and the herbage is rough with short hairs.[5] The 2–7 cm × 4–8 mm (0.8-2.8 × 0.16-0.32 inches)leaf blades are linear to narrowly elliptic. The heads of flowers have involucres that are mostly hemispheric (shaped like a globe that is cut in half), usually much less than 1 cm high (0.4 inches) or wide. The flowers have bright orange or sometimes yellow ray corollas,[4] but in cultivated plants, the flowers may be white or a variety of other colors.[6]
