Sun Tolerant Japanese Maples
Although some sources list some Japanese maples as sun tolerant, we believe that in the hot, dry foothills and Sacramento Valley, they will all benefit from some shade, especially in the afternoon. If you would like to try some in sunny areas we think that they would do better if there were no grass under the tree, there was 3-4 inches of mulch under the tree (but not touching the trunk), and the area is consistantly kept SLIGHTLY moist (not wet). With correct water practices, many Japanese maples, including many not listed here, will tolerate sun. The following varieties are a few of the more widely available Japanese maples that are known to do well in the sun.
This is the basic Japanese maple grown from seed, and is not grafted. It also provides the rootstock for all grafted varieties. Although there is some variability, most seed grown Japanese maples will take sun including those with both red and green leaves. Most turn either bright red or gold with red highlights in the fall. and can grown to a height of 20-25 feet.
The most popular of all red upright maples and is often the tree that most people think of when they think of a Japanese maple, tall and shapely with red leaves catching the sunlight. It holds its deep red color throughout the summer turning bright red in the fall. Viewing the leaves as the sun radiates through them in the summer is a memorable experience. It reaches a height of 20 feet, or taller in the right location. Laurie likes this classic variety. We have a young tree growing on the side of our pond.
This graceful upright tree readily stands the full sun. A vigorous grower eventually reaching a height of 20 feet, or sometimes more.

This beautiful weeping lace leaf maple that holds its deep red leaf color throughout the summer. It turns bright red in the fall. It is one of the more popular and readily available of the dissected type of Japanese maples. The mature shape is mounding, with very thick leaf coverage. Typical height is in the 5', taller if staked or trained, or with age, and can be kept lower.
The tree is similar in appearance to the classic "Bloodgood," however it has has a slightly faster growth rate and leafs out about two weeks later in the spring, an advantage in areas prone to late spring frosts. The deep red leaf color lasts throughout the season. In the fall the leaves turn to a fiery crimson. A vigorous, fast growing Japanese maple. We feel that Emperor I, Red Emperor, and Emperor are various names for the same cultivar.
Also called 'Dissectum Nigrum'. This tree has silvery leaves in the spring when the leaves first unfurl, turning to a good red in spring and summer. Late summer and early fall leaves sometimes change to a bronzy red depending on location, then to a bright red in autumn. Although very old specimens are quite large, typical height on this tree is in the 4-5' range depending on individual shape, training, and staking when young. An Ever Red is growing next to bench in the koi garden.
When backlit by the sun, the leaves glow like shards of stained glass in a cathedral window. The upright tree reaches a mature height of about 12 feet. The shape of the tree is fairly upright, often with a single trunk rather than multi-branching at the base. A nursery favorite.
An excellent cascading red leafed variety whose color lasts well into the summer. It is a bit more upright than other weeping forms with long arching red arms that sweep out away from the trunk. It is especially beautiful when planted on a mount or atop a rock wall where it can cascade. Fall leaf color is brick red.

Gold with extensive orange and red highlights in fall depending on location. Upright to about 10' tall. Takes some sun but has been newly added to our 'Sun Tolerant List' so we suggest cautious placement and care in the hottest locations.
This is one of the darkest (almost black-red) of the lace leaf maples. It retains this very dark color even in the heat of the summer. The stems of the new growth are dark red. It is one of the fastest growing of the dissectums. The fall foliage is a lovely crimson. Typical height is 6' or so, however can be higher with staking or age, or kept shorter.

OTHER TREES: Many other Japanese maples will take full sun, including many of the trees in the "Coralinium" group of maples, those with bright pink-red foliage in the spring like Shin DeShojo and Shin Chishio. Other less common but sun hardy trees include Beni Shi En, Shirazz, Red Baron, Sekka Yatsubusa, Oshio Beni, and the weirdly odd Hagaromo. The trees listed are only a few of the many sun tolerant Japanese maples.
