Threadleaf type Coreopsis, also known as tickseed, might be slow to wake up in Spring but it puts on a long-lived show once the heat of summer comes along. Dainty yellow flowers are the traditional type. Though many new hybrids range into pinks and reds. They all have a long bloom time and smother the plant in color. The foliage is light and airy and forms a nice mound. Blends with just about any color in the garden. Does best in well-drained soil.
