Early single-stem, or column-type stock in a highly uniform series for one-cut harvest. Aptly named for strong, straight, rigid stems. Iron performed well in our spring, early summer, and fall trials. Selectable for doubles and 55% double without selection. Compared to Katz, Iron is slightly later to flower, and has somewhat shorter and thicker stems. Tightly spaced florets on the flower spike make for compact 1 1/2-2", deep rose-pink blooms with a full appearance. NOTE: This variety produces one flowering stem per plant. Pinching is not advisable as it will terminate flowering.
• Edible Flowers: The peppery, clove-like flavor of the flowers lends itself well to use as a garnish on salads, desserts, and drinks.
DAYS TO GERMINATION: 7-14 days at 65-75°F (18-24°C). SOWING: Transplant — Sow 2 seeds/cell, 1/4" deep in 128-cell plug trays 5-6 weeks before last frost. Cover seeds lightly with vermiculite to help retain moisture. Transplant to cell packs or larger containers 14-21 days after sowing. Direct seed — Sow seed after last frost. SELECTION: Chilling seedlings causes visual differences that allow you to select for double-flowered plants by observing color, size, and shape of the cotyledon. After germination, while the seedlings are still in the cotyledon stage, expose the seedlings to temperatures of 40-45°F/4-7°C for 3-4 days. Select lighter green seedlings with an oval shape; these will produce double flowers. Discard very small seedlings, ones that are darker green in color, and those with rounder shaped cotyledons; these will produce single flowers. See our Stock Production Guide #8227 for more information on selection. LIGHT PREFERENCE: Sun. SOIL REQUIREMENTS: Well-drained, moderately rich soil. PLANT HEIGHT: Varies. Trellis, such as Hortonova, used as horizontal support, is necessary when the temperatures are consistently above 60°F (16°C) or where it rains frequently. PLANT SPACING: 6". HARDINESS ZONES: Annual. HARVEST: Fresh: Harvest when 1/3 to 1/2 the florets on stem are open. STEM LENGTH: 10-24". VASE LIFE: 5-10 days. 36-41°F (2-5°C) ideal storage temperature. USES: Excellent cut flower. Edible flower. Beds, borders, and containers. SCIENTIFIC NAME: Matthiola incana

Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.
90 - 105 Days
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
