Striped Maple

Acer pensylvanicum

Striped Maple is a small, shade-adapted understory maple with distinctive green-striped bark, best used in cool, moist woodland plantings.

Key Facts

  • Native understory maple of northeastern North America.
  • Small tree or large shrub with distinctive green- and white-striped bark.
  • Shade tolerant and best in cool, moist, humus-rich soils.
  • Produces small yellow-green flowers in spring followed by samara seeds.
  • Typically slow to moderate growing.
  • Valuable for woodland and naturalistic shade plantings.
  • Fall foliage often turns yellow before leaf drop.

Striped Maple is a small, shade-adapted understory maple prized for its green- and white-striped bark and gentle form. It suits woodland and naturalistic shade plantings where cool, moist soil is available but performs poorly in hot, dry sites.

Identification

Striped Maple, also called Moosewood or Snakebark Maple, is a small tree or large shrub that usually reaches 15 to 30 feet with a 10 to 20 foot crown. The bark shows distinctive vertical green and white striping. Leaves are maple-shaped and the tree produces small yellow-green flowers in spring followed by paired samara seeds. Fall leaves often turn yellow before dropping.

Best uses and where to grow

Use Striped Maple as an understory specimen in shaded or part-shade woodland borders, naturalistic shade gardens, and multi-layered plantings. It is suited to cool temperate sites roughly corresponding to USDA zones 3 to 7 and prefers sheltered sites with dappled light. Avoid hot, exposed locations where summer heat and drought stress can cause decline.

Planting and spacing

Space Striped Maple 10 to 20 feet from other trees or large shrubs to accommodate its multi-stem crown. Plant where soil stays cool and moist and set the root ball at the same depth it grew in the container or nursery field so the root flare is at soil level. Staking is generally unnecessary for established specimens.

Soil and watering

Choose moist, humus-rich, well-drained soil with acidic to neutral pH. Mulch and incorporate organic matter to retain moisture and improve fertility. In dry or compacted soils the tree will decline and leaves can scorch; consistent moisture during establishment prevents stress and supports steady growth.

After-flowering care and seasonal maintenance

Flowers are inconspicuous and followed by samara seeds; allow seeds to drop if naturalizing is desired. Prune sparingly to remove dead or crossing wood and to maintain desired form, preferably in late winter when structure is visible. Expect yellow fall color before leaves drop as the tree enters dormancy.

Controlling spread and naturalizing

Striped Maple commonly forms a multi-stem clump and can regenerate from root suckers and seedlings in suitable woodland settings. To limit spread remove basal suckers at the crown or cut them to the ground. Hand-pull or transplant volunteers while small to prevent unwanted thickets.

Propagation

Propagate primarily by seed with cold stratification to break dormancy. The species also establishes from root suckers and by layering, and occasional cuttings have been reported. Nursery production methods vary so confirm best practices for commercial propagation when scaling up.

Frequently asked questions

How fast does Striped Maple grow?
Growth is typically slow to moderate. Expect gradual height gain over several years with mature height commonly 15 to 30 feet once established.
Is Striped Maple suitable for a small garden?
Yes for sheltered spots if you can provide shade and moist, humusy soil. Allow 10 to 20 feet for its multi-stem crown and control suckers to keep it compact.
Does it need full sun?
No. It performs best in part shade to full shade. Hot afternoon sun increases irrigation needs and raises the risk of leaf scorch.
How should I water a young Striped Maple?
Keep soil consistently moist during the first two to three summers. Mulch helps retain moisture; prolonged dry soil leads to decline and visible leaf damage.
How do I propagate Striped Maple?
Use seed with cold stratification, or establish new plants from root suckers or layering. Cuttings are possible but less commonly used.
