Fall color and striped bark (particularly in winter) are attractive. Perhaps best for woodland gardens or shaded naturalized areas.
Acer pensylvanicum commonly known as snakebark maple is a shrubby understory maple that is native to moist, rocky forests from Wisconsin to Quebec and south in the Appalachians to Georgia. It typically grows as a large shrub or small tree to 5-8 m (15-25’) tall (less frequently to 12 m (40’) tall) with a rounded but uneven crown that is sometimes flat-topped. This is the only species of snakebark maple that is native to North America.
Key ornamental features are its interesting bark and fall color. Greenish bark on young branches and young trunks is vertically marked with distinctive white stripes (hence the common names of snakebark maple and striped maple). Stripes may vanish over time as older bark turns reddish brown. Obovate, double-serrulate, three-lobed leaves (to 17 cm (7”) long) emerge with pink hues in spring, mature to dark green by summer and turn bright yellow in fall. Leaf purportedly resembles a goose foot, hence the common name of goosefoot maple for this plant. Small yellow flowers bloom in pendant racemes in spring (May). Flowers give way to winged samaras. Moose and white tailed deer often browse the leaves and young twigs hence the common name of moosewood. Whistles can easily be carved from branch sections, hence the common name of whistlewood.
Easily grown in average, medium moisture, well-drained soils in part shade. Excellent shade tolerance. Plants dislike full sun conditions. Slightly acidic, consistently moist soils are preferred. Best performance occurs in cool summer climates.

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 +2-+8C (34-46F) 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 10-20 mm (1/4-1") deep into the soil, ensuring that the seeds are covered. Keep the soil moist until the seeds sprout.
