Plains coreopsis (Coreopsis tinctoria) is a vibrant and easy-to-grow annual flower native to North America. Also known as garden tickseed or golden tickseed, this member of the Asteraceae family is perfect for adding a pop of yellow to your garden. With its simple care requirements, plains coreopsis is an excellent choice for both novice and experienced gardeners.
Plains coreopsis thrives in full sun and well-drained soil. It prefers average temperatures between 65°F and 75°F (18°C-24°C). This hardy annual can tolerate a wide range of conditions, making it suitable for gardens across the United States and Europe where it has been introduced.
Sow plains coreopsis seeds directly into your garden bed in early spring after the last frost. The seeds should be planted in well-draining soil with a pH between 6.0 and 7.5. Water the area gently to keep the soil moist but not soggy. Once established, plains coreopsis is relatively low maintenance. Simply remove any weeds that compete for nutrients and water.
Plains coreopsis is generally resistant to pests and diseases. However, watch out for aphids, which can be controlled with insecticidal soap or a strong water spray. If the soil becomes too damp or poorly drained, your plants may develop root rot. To prevent this issue, ensure proper drainage before planting.
The vibrant yellow flowers of plains coreopsis bloom from midsummer through fall. They are perfect for cutting and bringing indoors to brighten up your home or office. You can also enjoy the beauty of these flowers by placing them in a vase or simply admiring their natural charm in your garden.
