Fothergill's Cosmos Double Dutch White

Details:

• Botanical Name: Cosmos bipinnatus 'Double Dutch White', a premium, highly refined selection within the Cosmos genus.
• Plant Class: Half Hardy Annual, establishing with incredible speed from a spring sowing to yield an abundance of pure white blooms in its very first season.
• Ruffled Snow-White Blooms: Features large, eye-catching double and semi-double flower heads with beautifully layered, crinkled petals surrounding a subtle, glowing golden central core.
• Stately & Bushy Growth: Displays a tall, upright, yet remarkably bushy and well-branched growth habit, reaching a mature back-of-border height of 90–120cm (36–48in).
• The Florist's Choice: An absolute triumph for home styling; the long, clean, straight stems and dense, volumetric white flower heads hold their form beautifully in water, providing a crisp focal point for fresh summer bouquets.
• Wildlife Support: The wide-open, accessible centers are a favorite foraging spot for local pollinators, while the maturing flower heads in late autumn produce high-quality seeds that attract hungry garden birds.
• Optimal Position: Thrives at its absolute best when positioned in a bright, open spot in full sun, demonstrating excellent natural resilience in poorer, well-drained soils where other annuals might struggle.

Care Instructions:

• Sowing Position: Start seeds early indoors from March to April in cellular trays of moist, free-draining compost, or sow directly outdoors in May where they are to flower once all danger of spring frost has safely passed. Position in full sun.
• Planting Out & Spacing: For indoor-started seedlings, gradually acclimatise them to outdoor temperatures before transplanting. Space the young plants approximately 30–45cm apart to allow their bushy, multi-branched framework plenty of room to mature smoothly.
• Maintenance: Avoid over-fertilising, as overly rich soil will encourage excessive leaf growth at the expense of blossoms. Support tall plants with subtle stakes in windy areas, and remove dead flower heads regularly to prolong the flowering season right up until the first autumn frosts.
