FamilyAsteraceae

Depending on the variety, cornflower is a perennial or annual plant, valued for its light, colorful, and very natural blooms. Its finely cut petals, often blue, mauve, pink, white, or purple, bring a rustic charm to flowerbeds, borders, pollinator gardens, and naturalized landscapes. Its delicate appearance pairs very well with grasses, yarrow, echinacea, daisies, and other prairie-style perennials.

Easy to grow, cornflower generally prefers a sunny location and well-drained, light to moderately fertile soil. Once established, it requires little maintenance and tolerates drier conditions quite well, making it an excellent plant for low-maintenance gardens, rockeries, embankments, and sunny borders. Removing faded flowers helps prolong blooming and keeps the plant tidier throughout the season.

Highly valued by bees, butterflies, and other pollinators, cornflower helps create a vibrant, colorful, and biodiverse garden. Some varieties are also excellent as cut flowers thanks to their delicate and decorative floral stems. It is an ideal plant for adding color, movement, and an elegant wild touch to outdoor spaces, while promoting the presence of beneficial insects in the garden.
