🍁 Sugar maple

Acer saccharum · Sapindaceae

🍁 North America
🧠 To remember it“Round sinus, sap abounds” — the rounded leaf lobes point to the sugar maple, the one whose sap has the highest sugar concentration of all North American maples.
Sugar maple — Acer saccharum

🔍 Identify it without mistakes

Large emblematic hardwood of Quebec and New England, featuring opposite leaves with 5 well-defined lobes and rounded sinuses (unlike the silver or red maple, which have sharper sinuses). Grey bark cracking into long vertical plates with age. Famous for its spring sap, the sweetest of all North American maples.

  1. opposite leaves with 5 lobes, rounded sinuses, margins sparingly or not toothed
  2. grey bark in long vertical plates on older trees
  3. pointed brown-maroon buds, opposite
  4. samaras (winged fruits) forming a very open U-shape
Size25-35 m
FloweringApril (before the leaves)
Habitatdeciduous and mixed forests, rich and well-drained soils, from southeastern Canada to the Appalachians and the Midwest

⚠️ Not to be confused with

No known dangerous confusionaucun

To tell them apart: opposite leaves with 5 lobes and rounded sinuses, alongside clear (non-milky) sap oozing from a broken petiole, confirm the sugar maple; all North American maples yield tapable sap safely

🍽️ Eating it

Partsspring sap, seeds (samaras, less commonly used)
Seasonsap from late February to early April, depending on freeze-thaw cycles
Tastefresh sap: barely sweet, thirst-quenching; reduced syrup: sweet, caramelized, woody

Preparation : collect the sap by tapping and drink it fresh (slightly sweet, close to water) or reduce it by evaporation into syrup (it takes about 40 liters of sap for 1 liter of syrup); tap holes must be closed and spaced out so you don't weaken the tree

💊 Healing with it

bark decoction traditionally used as an expectorant and tonic; spring sap considered remineralizing after winter

Level of evidence : traditional use — Cornell Maple Program — Sugar Maple sap and syrup guidance

⚠️ no notable toxicity; tapping must remain reasonable (minimum trunk diameter, a single tap per medium-sized tree) to avoid weakening the tree over multiple seasons

🪓 Other bushcraft uses

  • hardwood (hard maple) highly sought after in woodworking, flooring, and for musical instruments
  • sap fermented into a traditional slightly alcoholic beverage by some native nations
