Katz Hi Double White Stock Seed
90% double-flowering plants.
The same overall performance of the standard Katz series varieties, but now selected to produce 90% double-flowering plants. Long stems with 1 1/2–2", pure white blooms. Early blooming one-cut series. Performed well in our spring, early summer, and fall trials. Good uniformity in bloom time and stem length. Seedling selection for double flowers is not necessary; plants will yield 90% double blooms without selection. 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.

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.
