Safety Overview
1.Zinnia Grandiflora — Plant Snapshot
Zinnia grandiflora, commonly known as Rocky Mountain Zinnia or Plains Zinnia, is a captivating, low-growing perennial herb native to the arid and semi-arid regions of the southwestern United States and northern Mexico, particularly thriving across the Rocky Mountains, Midwest, and Southwest, including Texas, Arizona, and New Mexico. This resilient member of the Asteraceae (Compositae) family forms a dense, mossy mat of tiny, needle-like, bright green leaves, typically measuring around 1 inch (2.5 cm) in length. Its numerous much-branched, woody-based stems give the plant a robust, almost shrub-like appearance.
From late spring through mid-fall, Zinnia grandiflora produces an abundance of small, cheerful daisy-like flowers, approximately 1.5 inches (4 cm) across, characterized by bright yellow to orange ray florets surrounding a distinctive central orange cone. These prolific blooms not only add vibrant color to harsh landscapes but also serve as a vital nectar source, attracting a multitude of beneficial insects, including butterflies, moths, and bees. Growing to a compact height and spread of 4-8 inches (10-20 cm), this plant is highly valued for its exceptional drought tolerance, adaptability to poor soils, and its utility in xeriscaping, rock gardens, and for effective erosion control on sandy slopes.
