The flowers have a vibrant purple hue and are clustered together in a cluster, with some of the petals slightly overlapping each other. The leaves of the plants are a deep green color and the stems are thin and sturdy. The sun is shining down on the field, illuminating the flowers and giving them a warm, inviting glow.
