Seed Treatment
- Cold Stratify: Mix seeds with a small amount of moist sand or a damp paper towel.
- Seal them inside a plastic bag and refrigerate for 60–90 days at 35–40°F (2–4°C).
- Check regularly: If seedlings begin to sprout during stratification, gently remove them from the bag and plant them immediately.
Sowing Instructions
- After stratification, sow seeds indoors or in a greenhouse.
- Use a seed-starting mix and press seeds lightly into the surface—do not cover deeply.
- Keep the soil moist but not soggy.
Germination Details
- Germination Time: 30–60 days after stratification
- Maximum Total Germination Time: Up to 150 days
- Optimal Temperature: 68–77°F (20–25°C) during germination
Post-Germination Care
- Place seedlings in bright, indirect light.
- Once they develop several true leaves, transplant into larger pots or directly outdoors after the last frost.
- Space plants about 3–5 feet apart near a wall, trellis, or fence—they climb vigorously.
- Water regularly until established; drought-tolerant once mature.
- Prune as needed to control spread.
Tips
- Hardy in USDA Zones 3–9
- Grows rapidly and provides lush green summer foliage with brilliant red fall color
