Fireweed Seeds - Chamerion Angustifolium, 20 seeds

Quantity: 20 Seeds / pack

Fireweed (Chamerion angustifolium) is the tall pioneer wildflower of burned and cleared ground, sending up stately spikes of vivid pink-purple flowers in summer. In the garden it makes a dramatic back-of-border plant — but give it room, as it spreads by underground rhizomes once established.

Why choose our seeds?

• Tall spikes of vivid pink flowers in summer
• Tough, adaptable wildflower for sunny, open spots
• Spreads by rhizomes to form generous drifts — plan space accordingly

How to grow Fireweed seeds

Choose Your Planting Method

• Indoors: Surface-sow indoors 6-8 weeks before the last frost.
• Outdoors: Scatter outdoors in early spring as soon as the soil can be worked, or in fall for natural winter stratification.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Humidity dome or plastic wrap to hold moisture
• Spray bottle for misting

Sowing the Seeds

• Surface-sow: press the tiny seeds into moist mix and do not cover — seeds need light to germinate.
• Mist to keep the surface evenly moist.

Provide the Right Conditions

• Light: Bright light.
• Temperature: 60-68°F (15-20°C).
• Humidity: A humidity dome or misting keeps the fine seeds from drying out.

Germination

• 1-3 weeks.
• Seedlings are small and slow at first; thin or pot up when they have a few true leaves.

Transplanting

• After the last frost, when seedlings are sturdy.
• Harden off before planting out.
• 12-18 inches apart.

Care Tips

• Sun: Full sun.
• Water: Keep evenly moist; avoid waterlogged soil.
• Fertilizer: Generally not needed — heavy feeding can reduce flowering.
• Cut spent flower spikes before they open into fluff if you want to limit self-seeding.

Bloom Time:

Summer; plants can reach 6 feet tall in good conditions.
