The white flowered bush zinnia is also known as desert zinnia, spinyleaf zinnia, dwarf zinnia, wild zinnia and white zinnia. It is deer resistant. In Texas, it can be found in the Trans-Pecos, Southwest Rio Grand Plains and into the Valley regions. Soil pH should be acidic with a pH above 6.8. It has slender woolly stems and needle-like, 1/2" long, narrow, stiff, grayish-green leaves that have sharp tips. The number of bloom petals varies.

It grows 10 to 12 inches tall and to 2 feet in diameter which makes it a great groundcover. Requiring minimum care, the desert zinnia is useful in harsh arid environments. It is very drought tolerant and will survive with no supplemental water, but wll look a bit ragged and has fewer blooms. It will need a little water to grow to its optimum beauty and produce blooms prolifically. An occasional watering with a hose will suffice if it hasn't rained in a while. Soils must be well-drained soils. Itt makes a great xeriscape, rock garden or wildscape plant.
