Bachelor Button Tall Blue Cornflower Seeds (Centaurea cyanus) – 200+ Non-GMO Heirloom Seeds for Planting, Classic True-Blue Blooms for Beds & Bouquets, by Isla’s Garden Seeds, Gift Idea for Gardeners

Bachelor Button / Tall Blue Cornflower (Centaurea cyanus) is a cottage-garden favorite famed for its striking, sky-blue blooms on slender, branching stems. These long-stemmed flowers add vivid color to borders and cutting gardens, attracting butterflies while lending a fresh, classic look to arrangements.

Tall plants reach 24–36 inches and bloom prolifically from early summer, creating drifts of true blue that pair beautifully with poppies, daisies, and larkspur. Easy to grow and dependable, Bachelor Buttons thrive in sunny locations and well-draining soils, performing well in garden beds or naturalized plantings.

A superb cut flower, the blooms hold their color well both fresh and dried. Regular harvesting encourages new buds, extending the display over many weeks. Their airy habit and gray-green foliage provide soft texture throughout the season.

Beloved for charm, vigor, and versatility, Tall Blue Cornflower offers abundant stems for bouquets and a long, cheerful show in the landscape with minimal fuss.

🌱Planting Instructions

Approx seeds per order 200

Direct sow after the last frost or in late fall where winters are mild. Choose a sunny site with loose, well-draining soil. For earlier blooms, start indoors 4–6 weeks before the last frost and transplant carefully once hardened off.

Sow seeds 1/4 inch deep and thin seedlings to 8–12 inches apart for sturdy plants and plentiful stems. Keep soil evenly moist during establishment, then water moderately. Pinch young plants to encourage branching and more flower production.

Cut flowers when petals are just opening for longest vase life. Deadhead or harvest frequently to promote continuous bloom. Allow a few heads to mature if you’d like self-seeding for future displays.
