Acer negundo (Manitoba maple or box elder) Description: Manitoba maples are native to the Prairies and have been used extensively as shelterbelt, shade, and boulevard trees. They are fast growing with a high head and may attain a height of 10 to 13 m (30 or 40 ft) or more. Their life span is about 60 years. Their leaves are very untypical of maples and more closely resemble those of ash: pinnately-compound with 3 to 7 leaflets, each of which is irregularly lobed. Autumn color is a clear yellow. Male and female flowers are on separate trees with only female trees producing seeds. The female flower is greenish-yellow in drooping clusters. The male flower is a dense red tassel. Flowers appear before the leaves. The seed-containing samaras are winged and v- shaped, persist into winter, and constitute an important winter food source for birds. Problems associated with the Manitoba maple include a relatively weak structure (prone to breakage in wind, ice or with heavy snow loads); sensitivity to 2,4-D damage (are in fact considered an "indicator plant" to the presence of that herbicide); and the presence of several insects. Culture: They are adapted to full sun, a wide range of soils, and are fully hardy. They will not do well in shade. Infestations of aphids which excrete "honeydew" onto decks, picnic tables or vehicles are common. Manitoba maples are also beloved by cankerworms. Red and black box elder bugs lay eggs on the leaves and bark but seldom damage the tree. If wounded, the tree may produce an abundance of watersprouts from the base of the trunk. Use: Excellent in shelterbelts, farmsteads or acreages, they cannot be recommended for smaller urban lots due to their size and undesirable characteristics. They remain an excellent tree house and climbing tree. Manitoba maples provide food and cover for a wide variety of birds. They have been used as hedges. They may be taped for maple syrup. Propagation: Harvest seeds in mid-September and sown in spring. 33
