Thank You for looking up your Hardiness Zone. This information will assist you in determining whether a specific Japanese maple tree you are interested in will grow in your area. All of our Japanese maple trees grow in Zones 6-9, and many of them grow in Zone 5 as well. Please look up the tree you are interested in on our website, you will find a chart with the "Coldest Zone" and "Warmest Zone" listed for each tree.

Pacific Coast Maples takes a more conservative approach to Hardiness Zones because Zones 5-9 are where Japanese maples thrive and we want you to have an enjoyable experience with your new Japanese maple tree. 

On the other hand, J.D. Vertrees, the leading authority on Japanese maples, writes on page 47 of his world reknowned book Japanese Maples, "In North America these plants thrive in the soils and climates ranging from the rain-forest type of the Pacific Northwest to the very warm climate of southern California, and from upstate New York down the Atlantic seaboard to the southern states and throughout the Midwest. In Europe, they grow in the warm Mediterranean conditions of Italy, in the almost-pure-peat soils of Boskoop, Netherlands, and in the varied soils in Britain. They also thrive in many parts of Australia and Asia. 

After reading J.D Vertrees' scientific research on Japanese maples one begins to understand the versatility of these beautiful trees." Vertrees' lengthy research also shows that with correct mulching, "The exposed parts of most Japanese maple cultivars, once established, can withstand winter freezing and air tempuratures down to minus 18 degrees Celcius (0 degrees Fahrenheit) and below. The roots, however, can only survive to minus 10 degrees Celcius (14 degrees Fahrenheit)."
