Flowers give way to paired seeds with horizontally spreading wings (samaras to 2” long). Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Best in full sun.

Growing Instructions for the Norway Maple
The seeds have a period of dormancy. They can be planted outdoors in the fall or winter for spring germination or they can be cold stratified to simulate winter conditions and to break their dormancy at any time of the year. 1. Soak the seeds in water for several hours. 2. Put the seeds in a ziplock bag. 3. Put the bag in the refrigerator and leave it there for 4 months. 4. The seeds like moist, well-drained soil. Prepare a mixture of half potting soil and half sand, perlite or vermiculite. Put the soil in a pot. 5. Sow the seeds on the soil. 6. Cover the seeds with a layer of soil that is 1/4 of an inch thick. 7. Water the soil so that it is moist but not wet. 8. When the seedlings are a few inches tall, they can be transplanted.
