Flowers & Fruits: Bright yellow ray flowers to 2 or 3 inches across on 6 inches terminal or axillary peduncles.
Seasonal Color: Depending on geographical location, yellow daisy can flower most any time of year, and most heavily in fall and spring in the milder locations of the southwest United States.
Temperature: Best growth range is 35 to 90oF. Damaged by freezing or high temperatures.
Light: Full sun to partial shade in western shade in Phoenix is best.
Soil: Foliar chlorosis or yellowing is a very common problem in alkaline soils or when near pools where chlorinated water over splash is a problem. Elemental sulfur, nitrogen and iron-chelated fertilizers will correct this nutritional disorder. Prefers soils with good drainage.
Pruning: Yellow daisy requires little to no pruning and can easily be maintained at 3 to 4 feet in height by performing light heading cuts (light shearing) during the late fall. In coastal California landscapes, yellow daisy will tolerate severe renewal pruning.
Propagation: Yellow daisy is easy to propagate by vegetative softwood cutting.
Disease and pests: Snails and slugs, thrips.
