Flowers: The main attraction of perennial coreopsis is its tiny, daisy-like flowers. Coreopsis blooms come in a variety of colors, depending on the variety. Flowers typically bloom from spring through summer. Bees, butterflies, and other pollinators are attracted to the brightly colored flowers. 

Foliage and Growth Habit: Coreopsis flowers are topped on a green stem that also displays thin, grass-like foliage. The plant itself is deciduous and multi-stemmed, and has dense, upward growth. It can be expected to reach 24-36 inches in height and 18-24 inches in width.
