I love Japanese maples but here in mid Georgia the summers get really hot and the sun very intense. This means we have to plant most varieties of Japanese maple in partial shade (preferably afternoon shade).

In their natural habitat, Japanese maples grow in dappled forest sunlight and at the edges of woodlands. That being said, there are a few varieties of Japanese maple that have shown higher resistance to sun, even in the Deep South.

Here's a listing of some of the more sun tolerant varieties of Japanese maple.

Acer Palmatum
This is the original Japanese maple. It is grown from seed and it provides the rootstock for all grafted varieties. The tree has green leaves. 20 feet or more in height and spread. more details and photos
 

Bloodgood
The most popular of all red upright maples. Deep red leaves hold their color through summer turning bright red in fall. 20 feet or more in height and spread. more details and photos

Boskoop Glory
A graceful, vigorous growing upright tree that tolerates full sun. Leaves start out rosy-red in spring, deepening in color to plum red, then to a bronze-orange towards the end of summer, and finally a crimson-purple in fall. 20 feet or more in height and spread. more details and photos

Crimson Queen
The most popular of weeping, red lace leaf varieties. Deep red leaf color holds well through summer turning bright crimson-red in fall. Mounding growth habit. 5 feet or more in height and spread (taller if high-graft). more details and photos

Emperor I
Very similar to "Bloodgood," Emperor I has has a faster growth rate and leafs out about two weeks later in the spring, an advantage in areas prone to late spring frosts. Deep red leaves lasts throughout the season, turning fiery crimson in fall. 20 feet or more in height and spread. more details and photos
