（单词翻译）

 Coreopsis A stalwart perennial¹ in American gardens, the lanceleaf coreopsis is a native of the prairies of the Midwest. It is a plant with a sunny disposition². The daisy flowers have yellow petals³ that are toothed at the tips and bloom at the end of 18-inch long stems. If deadheaded regularly, many flowers are produced in cycles, throughout the summer. It makes a good cut flower. Coreopsis “lanceolata” has narrow well-shaped leaves and a height of 12-36 inches. The genus name, “coreopsis,” is from the Latin and means “bed bug” because the seeds are black, and they have a small hook on one end. A common name is tickseed, because the seeds have been likened to ticks. Our pioneers used the seeds to stuff mattresses⁴ and thought they repelled⁵ insects.
