Exceptionally robust stems, high yield, and uniform growth in the field or greenhouse. Bred for performance under short days and low temperatures; considered a group 2. In our trials, Costa did equally well for long day or summer production. This mix includes rose, silver (very light pink), white, velvet (burgundy), and apricot. Colors are subject to change depending upon availability.
•Edible Flowers: The flowers are a colorful garnish for use in salads, desserts, and drinks. The flavor is floral and slightly bitter, so use sparingly.
DAYS TO GERMINATION: 7-14 days at 70-75°F (21-24°C)
SOWING: Transplant (recommended) - Sow 8-10 weeks before last frost. Pinching encourages branching. Light is required for germination, but a fine layer of vermiculite covering the seeds can maintain moisture levels and prevent algae growth. Bottom water or mist lightly to avoid covering the seed with displaced soil. Transplant to packs or larger containers when the first true leaves appear, approximately 3-4 weeks after sowing. If desired, pinch back to 1 1/2-2" when the seedlings are about 3-4" tall to encourage branching. Direct seeding is not recommended.
LIGHT PREFERENCE: Sun/Part Shade.
PLANT HEIGHT: Varies.
PLANT SPACING: 4-12".
HARDINESS ZONES: Annual.
STEM LENGTH: 12-60" When grown as a one cut, stems can be as long as the full height of the plants. When grown for multiple cuts per plant, stems vary in length at 12-36".
VASE LIFE: 7-10 days
Ideal storage temperature 32-40°F (0-4°C).
HARVEST: Florets on lower 1/3- 1/2 of the spike are open.

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.
100 - 110 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.
Use for Cut Flowers and Bouquets
Variety good for fresh cut-flower displays.
Variety that we have found, based on our trials, to be the best performers in a climate-controlled greenhouse environment.
