Description

Peruvian daisy or shaggy soldier is a summer annual weed in the Aster family that is native to South America and central Mexico and has naturalized in many parts of the world. It grows either erect or sprawling and varies in appearance depending on where it is growing. This weed is commonly found in agricultural fields, container-grown ornamentals, landscape planting beds, lawns, gardens, and other disturbed areas. 

It generally has a 2-10 inch coarsely hairy stem and small flowers with 4-8 but generally 5 white rays surrounding the center yellow disc flowers. The ovate leaves are toothed and usually hairy.

This plant grows quickly in warm weather and can reseed aggressively, quickly forming colonies. It prefers full or partial sun, moist to dry conditions, and fertile loam or clay loam with high levels of nitrogen. 
 

Insects, Diseases, and Other Plant Problems: No significant problems. Weedy
