'Viburnum acerifolium' from the website Trees and Shrubs Online (treesandshrubsonline.
A deciduous bush 3 to 6 ft high; young branches at first softly downy, becoming glabrous. Leaves maple-like, three-lobed, the side lobes with divergent, slender points, all coarsely toothed, 11⁄2 to 4 in. long and about the same wide; rounded or heart-shaped at the base, with scattered down above, softly downy (especially at first) and covered with black dots beneath; stalk 1⁄2 to 1 in. long, downy. Flowers white, 1⁄5 in. in diameter, uniform and all fertile, produced during June in terminal, long-stalked cymes 2 to 3 in. across. Fruits first red, then purple-black, oval, 1⁄3 in. long.
Native of eastern N. America; introduced in 1736. Although one of the earliest introduced of American viburnums this is now very scarce in gardens; it has little beauty of flower, but is attractive in autumn for its crimson foliage. I have seen it growing along the roadsides in New Hampshire just as V. opulus does at home, but never so vigorous a shrub.
