Stock Incana Iron White

Stock Incana Iron White Seeds

Matthiola incana Iron White is part of the Iron series by Sakata Ornamentals. White is arguably the most essential and universally used color in professional cut flower production, offering the cleanest backdrop for all other colors, the strongest contrast effect, and the greatest versatility across every floral design style from minimalist to elaborate. In the Iron series, the white variety maintains the same tall, strong, and rigid stem structure with tightly packed florets, delivering a crisp and luminous spike that elevates any arrangement it joins.
White stock has a particularly strong presence in bridal, sympathy, and formal event floristry, where its combination of pure color, elegant form, and powerful fragrance makes it uniquely valuable. Approximately 55% of plants produce double flowers without seedling selection. Flower initiation requires nighttime temperatures below 15–18°C for 10–21 days, reliably available in Gulf winter conditions.
