The Story

Cornflower 'Red Boy' Seeds

Name: Cornflower Red Boy
Brand: The Foalyard
SKU: cornflower-red-boy
Availability: InStock

While the classic blue cornflower is an icon, 'Red Boy' brings a warm, vibrant energy to the patch. It produces masses of fully double, ruffled blooms in a rich shade of carmine-red (think crushed raspberries) that glow beautifully in the sunshine.

This variety has all the toughness and reliability of the wild blue type but with a sophisticated colour palette. Standing tall on silver-grey stems, it creates a "ruby and sapphire" effect when planted alongside blue varieties, or adds a punchy, jewel-toned highlight to white and pastel borders. It is a prolific cut flower—the more you pick, the more it blooms.

🌿 Understanding the Plant

Cornflower is a Hardy Annual.

It completes its life cycle in one season. Like its wild ancestors, it is incredibly tough and can withstand a British winter as a small seedling.

The "Autumn Secret": For the biggest, earliest, and most floriferous plants, sow the seeds in **September**. They will establish roots over winter and flower weeks ahead of spring-sown plants next year.

🌱 Growing Guide: How to Sow and Grow

Cornflowers resent root disturbance, so sowing them where they are to flower is best.

Germination:
Sow directly outdoors in Autumn (Sept) or Spring (March-May). Scatter seeds onto raked soil and cover lightly (3-5mm deep). Keep moist. Germination takes 14-21 days.

Where to Sow:
They demand **full sun**. They thrive in well-drained soil and are actually happier in "poor" soil than rich compost. Too much fertiliser produces lots of leaves but very few flowers.

Care While Growing:
Support: 'Red Boy' is a tall variety (up to 90cm). In windy gardens, give them a little support with twiggy sticks or netting to stop them flopping.
Deadhead: Snip off the dead flower heads regularly to force the plant to keep producing new buds until the frost.

🤝 Perfect Garden Companions

The raspberry-red of 'Red Boy' works beautifully in patriotic or jewel-toned themes:

🔵 Cornflower 'Blue Ball': The Classic Contrast. Planting Red, White (Snowman), and Blue cornflowers together creates a vibrant, patriotic "Union Jack" display that hums with bees.
☁️ Ammi Majus (Queen Anne's Lace): The Florist's Mix. The flat, white lacy heads of Ammi provide a calm, neutral background that makes the red cornflowers really pop in a vase.
