COLD STRATIFICATION:
Place the seeds in a damp paper towel inside a sealed plastic bag and refrigerate for 6–8 weeks. Check periodically—if seedlings begin to emerge during stratification, remove them from the bag immediately and plant them in moist soil.
When to Start
Start seeds indoors in late winter to early spring, or sow outdoors in fall to allow natural stratification.
Sowing Instructions
- Soil: Use a well-draining seed-starting mix.
- Depth: Sow on the surface and lightly press into the soil—do not cover; seeds need light to germinate.
- Moisture: Keep the soil consistently moist but not waterlogged. Mist gently to avoid displacing seeds.
- Temperature: Ideal germination temperature is 18–22°C (65–72°F).
Germination Time
Seeds typically germinate in 30–90 days, but may take longer depending on conditions and stratification success.
Post-Germination Care
Once seedlings develop their first true leaves:
- Transplant into individual pots with rich, well-draining soil.
- Place in a bright, indirect light location.
- Gradually harden off young plants before transplanting outdoors after the danger of frost has passed.
Outdoor Planting
- Location: Full sun to partial shade.
- Soil: Tolerates a range of soil types but prefers moist, loamy soil.
- Spacing: Plant 60–100 cm (24–39 in) apart.
- Watering: Water regularly during establishment; drought tolerant once mature.
Tips
- This fast-growing shrub spreads by suckers—plant where it has room to expand or control spread by removing unwanted shoots.
- Cut back in late winter or early spring to encourage fresh growth.
