Overview
Also known as cornflower, this charming annual was once so common in European grain fields that it became the national flower of several countries. Its brilliant blue petals are a true blue — one of the rarest colors in the plant kingdom. Bachelor buttons are edible, easy to grow, and self-seed freely, making them a carefree addition to wildflower meadows and cottage gardens.
