Iron Rose Stock Seed
Premium, reliable florist quality.
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", dark rose-red 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.
Ht. 24–28". Avg. 17,000 seeds/oz. Packet: 50 seeds.
SOWING: Transplant (recommended) - Sow ¼" deep into 128-cell plug flats 5-6 weeks before last frost. After danger of frost has passed, harden off plants and transplant to the field or protected structure. Direct seed - After last frost. Do not pinch plants. Succession-plant every two weeks for multiple harvests. Stock is a cool-weather crop. Spring and fall-blooming successions are optimal. Stock is a member of the Brassica plant family and is susceptible to flea beetle predation. To prevent flea beetle damage, cover plants with row cover at the time of transplanting. SELECTION: Selection for double-flowering plants is a difficult and time-consuming process. For most situations, we recommend finding a use for the single-flowering plants rather than conducting selection. Chilling seedlings causes visual differences that allow you to select for double-flowered plants by observing color, size, and shape of the cotyledon. While 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 details and information on selection.
