Coreopsis (common names include tickseed and calliopsis) is a genus of herbs in the family Asteraceae. This group of plants is related to sunflower. The plants may be from one and a half feet to four feet (46 to 120 centimeters) high. The flat fruits are small and dry and look like bugs. Many of its 35 to 114 species are cultivated.
Twenty-eight species are native to North America and the others come from Central and South America. The flowers are usually yellow with a toothed tip. They have showy flower heads with involucral bracts in two distinct series of eight each, the outer being commonly connate at the base. The name Coreopsis is derived from the Greek words κορις (koris), meaning "bedbug," and (opsis), meaning "view," referring to the shape of the achene.
Grow Coreopsis from seed.
Directly seed them into your flower garden in early spring. Sow seeds early in the season, covering lightly with coarse or sandy soil. Keep the soil moist until they germinate, about one of two weeks.
