Bright and bold, sunflowers are loved by bees, birds, and just about everyone. The name of their genus, helianthus, comes from the Greek words for sun (helios) and flower (anthos). These annual plants are known for their large, daisy-like flowers and radiant charm. While sunflowers come in shades of red, orange, and maroon, it's the classic yellow blooms with brown centers that are the most common.
