Not our old fashioned garden zinnia, only, our native zinnia for most of the Midwest, West and Southwestern parts of the United States. A terrific low growing and spreading groundcover for poor soils and little water. Rugged! A survivor without being a pest!

This is a good example of traditional garden books not really knowing plants native or adaptable to our region. In Flora, a Gardeners Encyclopedia, Zinnia grandiflora is listed as a USDA Zone 9-11 plant.

Propagate by root division in fall or springtime. Water monthly for continuous blooming.

Another low water-use zinnia to try is Zinnia acerosa, a semi-woody shrublet with small white flowers. Z. acerosa grows to 10” tall and spreads to 15”.

Use in Garden
