New! Double-flowering, premium-quality blooms and stems.
"Hi-double" plants produce 90% or more double-flowering plants. From the same breeder as the Iron Series, Early Arrow is very similar to Iron in overall performance with very straight, strong stems and highly uniform plants. Long stems with 1 1/2–2", pure white blooms. One-cut series. Performed well in our spring, early summer, and fall trials. Seedling selection for double flowers is not necessary; plants will yield at least 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.
- Avg. 15,600 seeds/oz
- Packet: 50 seeds
DAYS TO GERMINATION: 7-14 days at 65-75°F (18-24°C)
SOWING: Transplant (recommended) – Sow ¼" deep into 128-cell plug flats 5-6 weeks before transplanting out into the field or protected structure. Direct seed – After danger of 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.
