Paperbark maple is a small, oval to rounded deciduous tree native to central China. It has distinctive three-parted leaves of dark green that turn orange-red and bronze tones in fall. This tree is best known for its beautiful, peeling coppery cinnamon bark, which looks lovely year-round.
Paperbark maple does best in sites with moist, well-drained soil and full sun to partial shade. The winged fruits of this maple are usually sterile, so it is not weedy. Though slow growing, this highly attractive tree is well worth the wait. It is best enjoyed in the landscape as a feature plant. (source learn2grow.com).

|Germination||1. Start the cold stratification process one month before the beginning of spring.|
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 but no longer than 48 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 34 to 46 degrees Fahrenheit for a minimum of 35 days, but not longer than 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 1/4 to 1 inch deep into the soil, ensuring that the seeds are covered. Keep the soil moist until the seeds sprout.
