Corncockle 'Bianca' Seeds
(White Agrostemma)
Corncockle Bianca is an elegant variety with large white flowers on long, straight stems. Once a common sight in the cornfields, now corncockles are more often seen growing in a beautiful cottage garden border.
Bring a touch of ethereal grace to your garden with Corncockle 'Bianca'. This beautiful hardy annual produces tall, slender stems topped with silky, pure white flowers that shimmer in the breeze. It's incredibly easy to grow from seed and perfect for creating a romantic, naturalistic look in 'white gardens', borders, or a mini-meadow. It's also a wonderfully delicate cut flower.
Perfect for autumn sowing! See our full Seeds to Sow in October collection. A fantastic choice for easy, naturalistic planting – explore the Direct Sown Seeds collection and our Cottage Garden Seeds collection! Love Corncockles? See the classic Pink Corncockle seeds too!
