Amur maple, or Acer ginnala, is an attractive tree with red fruit in summer and brilliant fall color. Amur maples are very hardy trees with round form. Serviceberry is an excellent landscape choice. Downy Serviceberry, Amelanchier arborea, tolerates various soil conditions and shade. White flowers produce edible fruits, and the foliage is yellow to red.
Hawthorns are good choices and are very adaptable trees.
Cockspur hawthorn, Crataegus crus- galli, has white flowers in spring, glossy foliage all summer, and brick red fruit in fall. Be aware of dangerous long thorns, especially with children in area. The cultivar 'Inermis' is thornless. Finally, the magnolias are popular flowering trees of spring. Saucer magnolia, or Magnolia x soulangiana, has large pink flowers.
