Did you Know? Because of its brilliant red color in the fall, Red maple is prized as an ornamental. The sap can be used for producing maple syrup, however its sap has only about half of the sugar content as sugar maple. Native Americans used rep maple bark as an analgesic, wash for inflamed eyes and cataracts, and as a remedy for hives and muscular aches.

Identification Hints: There are many native and ornamental maples. Red maples are distinctive in having the red flowers emerge a week or more before the leaves. Silver maple (A. saccharinum) has greenish-yellow flowers that emerge well before leaves and has large 5-lobed leaves with whitish undersides (only 3 main lobes in red maple). The other ornamental maples generally have green undersides of the leaves (as contrasted with white or gray in red maple) and usually do not have red flowers.
