Plains Zinnia, Rocky Mountain Zinnia, Prairie Zinnia, Little Golden Zinnia, Yellow Zinnia, Golden Eye, Wild Zinnia, Crassina grandiflora


Zinnia grandiflora (Plains Zinnia) is a low-growing, sturdy perennial forming a mossy mat of tiny, needle-like, bright green leaves, 1 in. long (2.5 cm). Its numerous much-branched woody-based stems give the plant a shrub appearance. In late spring to mid fall, a profusion of small bright-yellow ray flowers, 1 1/2 in across (4 cm), adorned with an orange eye cover the plant. They attract a multitude of beneficial insects, including butterflies, moths, and bees. Native to Rocky Mountains and south into Mexico, Zinnia grandiflora is ideal for dry, gravelly rock gardens, parkways, as well as well-drained flower gardens. This mounded perennial slowly spreads by rhizomes to become a showy groundcover. It is also good for erosion control on steep, sandy slopes. Durable, water-wise, tolerant of drought, severe heat, strong winds, and cold temperatures, Zinnia grandiflora provides a long season of interest in the landscape.

  • Forms a dense, compact mound up to 4-8 in. tall and wide (10-20 cm).
  • Thrives in full sun to part shade in occasionally to very dry soils. Good drainage is important. Drought tolerant.
  • Great choice for beds and borders, slopes, prairies and meadows, coastal gardens, containers.
  • Can be propagated from seeds or cuttings. Cuttings or division should be done in the spring.
  • Native to most of the Midwest, West and Southwestern parts of the United States.
