Cornflower is distinguished by its vivid blue flowers, which bloom atop slender stems that can reach up to 2-3 feet (60-90 cm) in height. The foliage of this annual consists of lance-shaped, gray-green leaves. Its flowers are thistle-like in appearance, with a ring of ragged, tubular petals. This plant thrives in full sun to partial shade and prefers well-draining soil, showing a remarkable tolerance to low-water conditions. When planted in too much shade or overly rich soils, the stems may become weak and require support.
