Product DescriptionOverview and what to expect

Cornflower Double Black Seeds produce dramatic double blooms in rich deep maroon shades that appear almost black, creating bold contrast in sunny borders and cutting gardens. Easy to grow and highly effective when paired with brighter flowers, these hardy annuals flower from June to September and add depth and texture to mixed planting schemes. The upright plants are attractive to bees, butterflies, hoverflies and pollinators, making them ideal for wildlife-friendly gardens as well as floral arrangements. Growing to around 90cm tall, they bring striking colour and elegance to summer displays.
