Shade trees — oaks, maples, hickory, and poplar — would accomplish that goal as well. But Cunningham said that the city’s parks are relatively well stocked with shade trees, which grow quickly and reach great heights. Though they turn spectacular hues of crimson, orange and gold in the fall, in the spring their flowers are small and relatively insignificant. In contrast, the ornamentals are shorter and their fall colors are more muted. But each spring, they are adorned with showy, fragrant flowers that bloom practically at an adult’s eye level.
