Coreopsis (also known as plains tickseed, or Calliopsis), is a long-lasting wildflower with soliatary, daisy-like flowers (usually between 1" and 2" diameter) with bright yellow ray flowers contrasted by burgundy and maroon-colored center disks. Its genus name, Coreopsis, comes from the Greek words koris (bug) and opsis (resembling), as its seeds have a striking resemblance to ticks--hence one of its common name, "tickseed".
Flowers will arrive in bouquets ranging from fully-opened to fully-closed flower heads. Closed flower heads will open over the course of a few days. Flower heads have a tendency to explode with color that brightens over time. They should last 10-14 days with proper care.
