Performed well in our spring, early summer, and fall trials. Good uniformity in bloom time and stem length. 55–60% double-flowering without selection; some selection possible.

DAYS TO GERMINATION: 7-14 days at 65-75°F (18-24°C).

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.

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.
