Hardiness zones
Sunset 8, 9, 12-24
USDA 9-11
Landscape Use: Accent, garden border, low informal screen or hedge. Commonly used as landscape filler plant.
Form & Character: Herbaceous to lightly wooded perennial, bright, festive, alive, free flowering.
Growth Habit: Fast, upright and stiffly branched to 6' in height with equal spread. Stems and branches are brittle and break easily.
Foliage/Texture: Leaves are normally gray, densely pubescent (though cultivar 'Viridis' is lacking pubescence so leaves are green), and pinntified leaves to 2" long; medium texture.
Flowers & Fruits: Bright yellow ray flowers to 2.5" across on 6" terminal or auxiliary 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.
Watering: Regular
Pruning: Yellow daisy requires little to no pruning and can easily be maintained at 3' to 4' 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
Additional comments: Cultivar 'Viridis' is a very common green-leaved variant, especially in the Phoenix area. Cultivar 'Munchkin' is a dwarf, only 3' tall.
