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 most Japanese maples, including many not listed here and especially those with red leaves, 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. Copies of our Sun Tolerant List are available in the nursery office. Lace-leaf, cascading Japanese maples are indicated below with italics.
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. It can reach 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.
Graceful upright tree and a vigorous grower eventually reaching a height of 20 feet, or sometimes more. Really great red color, turning from rosy red in the spring, to plum red ,to bronzy orange as the summer ends, the crimson-pruple in fall. Similar tree to Oshio Beni. Boskoop Glory is one of Joe's favorite trees.
Similar to Bloodgood, slightly more upright so we often have these in a multi-trunk version that accents this form. To 20'. Sun enhances the red leaves. Crimson in fall.
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. Typical height might be 6' tall, but can be taller with staking or with age, or can be kept lower. A beautiful specimen cascades over the waterfall in our koi garden.
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. A specimen is growing near our koi pond.

Imagine red on one side of the stem and yellow on the other. Exquisite! The leaves are light green, turning gold in the fall with red highligts. Upright growth to 15-20 feet. Vigorous, puts on growth more quickly than many other Japanese maples. Coral bark eventually turns gray as it matures but new growth is always coral. As with all coral bark maples, the tree may show leaf burn in locations with excessive sun and heat.

This weeping tree grows into a low mounding shape that is slightly taller than wide. Typical height might be 5' but can be kept lower, or staked higher, or with age. This tree has been newly added to our sun tolerant list at the suggestion of many customers and staff, so we still suggest careful placement and care in the hottest locations.
This Japanese maple has been available for over 100 years. It is best known for its intense fall crimson color. It appears to glow.

This is the only upright growing dissectum among the Japanese maples. It is covered with small, light green, lacy leaves lightly tipped with reddish tints as it first unfolds in the spring. Summer color is a nice, bright green that takes sun well. Fall colors are spectacular and range from solid reds to vivid gold with strong red highlights, depending upon location.
