Habitat: Grows on wooded bluffs in extreme northeast Iowa.
Hardiness: Maples vary in hardiness. Most fall into zones 4 through 8, but some are less tolerant of cold or heat than others. When selecting a maple tree, be sure to select a species suited for Iowa's weather.
Growth Rate: Maples vary in growth rate. Maples that are fast growing tend to have weak wood and may suffer from wind and ice damage. Slower growing Maples have heavier, harder wood, making them less susceptible to branch and limb drop.
