Crimson King is a majestic looking maple tree for large gardens, parks, and city avenues. Its palmate leaves are dark crimson red, almost black, and glossy, turning orange-red in autumn. In the spring, just as leaves emerge, it flowers profusely with many small yellow flowers, typical for many Norway maples. In the fall, the leaves turn brown, dark maroon or bronze before dropping.
Majestic, award-winner tree. Excellent as a shade tree or specimen to add accent to the landscape.
Grow it in any well-drained soil. Wind and air-pollution tolerant. Fully hardy to -40°C

1. Start the cold stratification process in the end of the beginning of the year.
2. Place the seeds in a glass bowl and cover with room temperature water. Allow the seeds to soak for a minimum of 24 hours.
3. Hold a handful of sterile peat planting medium under a running faucet until the peat is soaked. Squeeze most of the water out of the peat, leaving it moist but not soggy. Place the moist peat into a zip-lock plastic bag.
4. Remove the seeds from the bowl of water and rinse them off under clean running water. Place up to three seeds into the plastic bag containing the peat. Use more peat and plastic bags if you want to germinate more than three seeds.
5. Push the seeds into the peat and seal the plastic bag. Shake the bag to distribute the peat so that it covers the seeds completely. The seeds must be buried in the moist peat in order to germinate.
6. Place the sealed bag in the bottom of the refrigerator. This will serve as the cold stratification. The seeds need to be kept at +4-+7C (34-46F) for 90 days.
7. Open the plastic bag periodically to make sure the peat is still moist. Add water as needed to restore the moisture.
8. Check the weather forecast after 35 days. You can plant the seeds outdoors if all danger of frost has passed. You can wait up to 55 more days, if there is still a possibility of frost and plant the seeds as late as early summer.
9. Plant the seeds by removing them from the peat and rinsing them with clean water. Bury the seeds ensuring that the seeds are covered. Keep the soil moist until the seeds sprout.
