Previously known as:

Phonetic Spelling
ZIN-ya ay-ser-OH-suh
Description

Desert zinnia is a low-growing, rounded, deciduous perennial in the Asteraceae (aster) family and is native to Mexico and the southwest United States, specifically Arizona and Texas,. It has a woody base and herbaceous stems that become woody with age from the bottom up. It can be found growing in prairies, plains, meadows, pastures, and savannas at higher elevations.  

Desert zinnia requires full sun to partial shade and well-drained soil. It will tolerate clay, sand, and shallow rocky soils. Give it 1 to 3 feet of growing space. It will bloom sporadically from spring to fall as long as moisture is available. It may go dormant during long periods of drought. Prune in spring after the last frost to remove winter damage. Cut to the ground every few years to rejuvenate the plant. Propagate desert zinnia by division or seed; seeds are most plentiful on the plant in the fall. 

The plant is used in the restoration of disturbed areas, in naturalized areas, on a slope or bank, and in wildlife and pollinator habitats. It is also a good addition to butterfly, rock, native, and drought-tolerant gardens and grows well in a container.   

Insects, Diseases, and Other Plant Problems:  Over watering can cause root rot. Periods of high rainfall can contribute to flower blight. Young plants may be consumed by rabbits and ants.  Transplanting is difficult due to the plants' deep taproot. 

The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common zinnia insect pests and diseases.
