Large-flowered tickseed

Large-flowered tickseed (Coreopsis grandiflora) is a perennial herbaceous plant belonging to the Asteraceae family. This species is widely recognized in professional landscaping and horticulture for its vibrant golden-yellow blooms and long flowering season, making it a staple in various decorative plant production systems.

Native to North America, the plant has established a global presence due to its ecological adaptability. It thrives in various temperate regions, where it is cultivated both for ornamental use and as a low-maintenance perennial in public park systems and private gardening enterprises.

Botanically, the plant develops bushy, erect stems that typically reach heights between 30 and 60 centimeters. The foliage is characterized by deeply lobed or divided leaves, while the flowers are prominent daisy-like heads. These heads can be single or semi-double, offering significant visual appeal throughout the summer months until the first autumn frosts.

Agronomic requirements are focused on providing a high-quality environment for vigorous growth. The crop prefers well-drained, fertile soil and requires full sun exposure to maximize flower production. Adequate spacing between plants is essential to ensure proper air circulation, which helps in preventing moisture-related physiological issues or fungal infections.

The main agricultural and horticultural application is ornamental landscaping. The species is susceptible to certain pathogens, such as powdery mildew, and insect pests like aphids. Integrated pest management, involving regular scouting and the use of targeted biological or chemical treatments when necessary, ensures the health and longevity of the plantings in commercial production settings.
