A genus of highly ornamental, hardy, deciduous trees or shrubs greatly valued for the effect produced either when planted in group-form in our large grounds or when growing as single trees on the margins of lawns or again as sidewalk trees on sheltered streets. The Maple loves a sheltered situation in a soft moist soil, and plenty of water at the root during the growing season.
Acer negundo stands exposure better than any other species, and, in good soil, makes a fine shade tree even when given considerable exposure. Acer macrophyllum, our native species, becomes a handsome tree of large proportions with a stately stem often three feet or more in diameter and branches to the height of twenty feet, its spread of limbs shading an area from seventy-five to one hundred feet across.
Acer campestre, the English Maple, is a small tree with small cordate leaves.
Acer Japonicum, the Japanese Maple, and its varieties make an effective shrubbery group, their deeply cut, variously tinted leaves being very beautiful.
Acer saccharinum, the Sugar Maple, is one of the very best of our deciduous trees. Where given good soil and a situation not too greatly exposed it makes a fine tree either for the sidewalk or as a single specimen on the lawn.
Acer Schwedleri gives beautiful color effects in early Spring and also in the Fall.
Our native Acer circinatum, the dwarf species of Acer Japonicum and its varieties, and the many varieties of Acer palmatum make beautiful shrubs early in Spring when the young leaves first open, and again in the Fall when they take on their Autumn tints of red and yellow.
Propagate by seeds sown, as soon as ripe in Autumn, in the open ground, covering the seeds about one-quarter of an inch deep. The rarer varieties and the variegated forms are propagated by grafting in Spring or by budding in Summer on the common species.
