Stock Incana Early Iron White

Stock Incana Early Iron White Seeds

Matthiola incana Early Iron White is part of the Early Iron series by Sakata Ornamentals, developed as a targeted improvement over the standard Iron series for production during the months with the shortest days and lowest light levels: November, December, January, and February. During these critical months, Early Iron delivers better uniformity, higher harvested quality, and greater production quantities than the standard Iron series, making it the preferred choice for professional growers who need reliable output during the peak Gulf winter production window.
The white variety within Early Iron carries all the structural advantages of the Iron series — tall, rigid stems, very tightly spaced florets, and approximately 55% double flowers without seedling selection — while adding the critical advantage of extra-early flowering initiation under short-day conditions. This makes Early Iron White the most practical white stock option for Gulf winter cut flower production where the season’s best output must align with the cooler months.
