Flower Stock Iron Blue delivers premium florist-grade quality with striking deep blue coloring and superior stem architecture, making it an exceptional choice for sophisticated floral arrangements and professional cut-flower production. These Non-GMO heirloom seeds produce early, single-stem column-type plants yielding one premium flowering stem per plant—engineered for efficient one-cut harvest and maximum productivity. Iron Blue's aptly named rigid, straight stems reach 24–28 inches and support tightly spaced florets creating compact 1½–2 inch flower spikes in rich, saturated blue with a full, luxurious appearance. The variety demonstrated outstanding performance across spring, early summer, and fall trials, with natural double-flower production at 55% without selection and selectable for higher double rates through careful breeding. Compared to Katz, Iron blooms slightly later with somewhat shorter, thicker stems—a beneficial trade-off that enhances durability and improves vase longevity. Stock Iron Blue's peppery, clove-like flavored blooms also serve as sophisticated edible garnishes for salads, desserts, and beverages. With a 100-day harvest window and 60% or better germination rate, this variety ensures reliable, premium results. Important: Do not pinch plants, as this terminates flowering. David's Garden Seeds® provides these sustainable, Non-GMO seeds in environmentally responsible, reusable, and fully recyclable packaging.
