How to Identify Norway, Sugar, and Black Maples — And Why It Matters in Bloomington, IN Landscaping
If you’re planning to plant trees in Bloomington, Indiana, knowing the difference between native and invasive maples is essential. At Wells Lawn Care and Landscaping, we help homeowners make smart, sustainable tree choices that benefit the local ecosystem.
Norway Maple vs. Sugar and Black Maple: What’s the Difference?
At first glance, Norway, sugar, and black maples may appear similar. However, there’s one key difference: Norway maple (Acer platanoides) is invasive in Indiana, while sugar maple (Acer saccharum) and black maple (Acer nigrum) are native species that support local wildlife and ecology.
Here’s how to tell them apart and why it matters for your Bloomington landscaping.
Leaf Shape and Lobes
- Norway maple typically has 5 to 7 lobes (usually 7)
- Sugar maple usually has 5 evenly shaped lobes
- Black maple has 3 to 5 lobes, often appearing as just 3 due to the drooping lower lobes
Pro Tip from Wells Lawn Care: Black maple leaves tend to droop slightly at the sides, looking wilted which can help identify them when choosing native trees for your yard.
Seed Structure (Samaras)
- Norway maple seeds spread out like a handlebar mustache
- Sugar and black maples have downward pointing samaras, more like a Fu Manchu mustache
Sap Color
- Norway maple releases a milky white sap
- Sugar and black maples release clear sap
This simple test can help Bloomington homeowners avoid accidentally planting an invasive species.
Other Identifiers
- Black maples have stipules (leaf-like growths) and hairy undersides
- Norway maple often has broader than long leaves and hairy vein axils
- Bark, bud shape, and fall foliage color also differ across species
Why Avoid Planting Norway Maples in Bloomington?
Although attractive, especially cultivars like ‘Crimson King’ with deep red leaves, Norway maples are invasive in Indiana. They:
- Crowd out native trees like the sugar maple by forming dense shade canopies
- Support fewer native insects, which in turn feed fewer birds
- Serve as hosts for destructive pests like the Asian long-horned beetle, threatening other hardwoods
- Are more tolerant of deep shade than native maples, enabling them to dominate forest understories

Wells Lawn Care and Landscaping encourages residents to choose native trees that support Indiana’s environment and resist pests naturally. Sugar and black maples are excellent options that offer beautiful fall color, provide shade, and support native wildlife.
