Product Description
Cornflower Black Ball is a gorgeous pollinator-friendly annual bloom. It will produce rounded flowers in rich shades of crimson throughout the summer, attracting bees and butterflies with ease. They can grow quite tall, and as their stems are on the thinner side, they may need support. Leave seeds if you wish after flowering, as they can provide food for birds.
