Black Maple (Acer nigrum)



The black maple is a hard maple with seed that matures in fall.  It is very similar to the sugar maple, and is excellent for sap collection. The sap can be used to make maple syrup and maple sugar. It has slightly different looking leaves and keys from the sugar maple and is often found on wetter, heavier soil than that preferred by sugar maple. The Ottawa area has an abundant isolated northern population of black maple, with most of the geographic range for this tree being farther south and west of us.  It can hybridize with sugar maple and some tree experts consider it a variety of sugar maple. The black maple grows to a height of 20 to 30 meters tall, with a straight trunk and a rounded open crown. The hard maples take about 30 years to mature.
