Coffret Seeds - Flower, 30 seeds

Quantity: 30 Seeds / pack

Coffret is a modern cut-flower rose variety noted for cup-shaped blooms in an unusual purple-and-green color combination, with densely packed petals and green-tinted outer petals. Grown from seed, it is a project for patient rose lovers: rose seeds need a long winter-like chilling period to sprout, and seedlings will be unique plants rather than exact copies of the named parent.

Why choose our seeds?

• Seeds of the distinctive Coffret cut-flower rose, with its unusual purple-green coloring
• A rewarding long-term growing project for rose enthusiasts
• Each seedling is one of a kind — no two seed-grown roses are exactly alike

How to grow Coffret seeds

Choose Your Planting Method

• Indoors: Start the chilling treatment in late fall or winter so seedlings are ready for spring.
• Outdoors: In cold climates, seed can be sown outdoors in fall to chill naturally over winter.

Prepare Your Materials

• Seed-starting trays or small pots
• Well-draining seed-starting mix
• Damp paper towel or vermiculite and a sealed bag for chilling
• Spray bottle for misting

Sowing the Seeds

• Soak seeds in water for 4–6 hours, then place in a damp (not wet) paper towel or vermiculite inside a sealed bag.
• Chill in the refrigerator at 36–40°F (2–4°C) for 8–12 weeks to break dormancy; check occasionally for mold and for early sprouts.

Provide the Right Conditions

• Light: Bright, indirect light for young seedlings.
• Temperature: 70–75°F (21–24°C) after the chilling period.
• Humidity: Keep the medium evenly moist but never soggy.

Germination

• After chilling, sow 1/4 inch deep in seed-starting mix.
• Germination is slow and uneven, often taking several weeks to a few months — keep the tray warm and moist and be patient.

Transplanting

• Pot up seedlings individually once they have several true leaves.
• Move outdoors after frost into full sun, spacing plants 18–24 inches apart.

Care Tips

• Sun: Full sun.
• Water: Water deeply and regularly; roses dislike drying out.
• Fertilizer: Feed established plants during the growing season.
• Seed-grown roses vary — thin to the strongest seedlings if growing several.

Bloom Time:

Seed-grown roses are slow to establish; flowering on mature plants occurs during the warm season, and seedlings will not be identical to the named Coffret parent.
