Japanese maple trees (Acer palmatum) are prized for their delicate and colorful foliage throughout the growing season, including during fall. Generally hardy in USDA zones 5 to 8, this tree is a smallish, slow-growing species, with mature heights of 4 to 30 feet, depending on cultivar. Although the tree blooms in spring, it is the delicate palmate leaves with 5, 7, or 9 toothed lobes that offer the real appeal. The foliage offers striking color throughout the growing season, becoming even more beautiful with the fall color change.
There are many recommended cultivars that produce the familiar red-colored foliage, but there are also cultivars that provide brilliant green or gold tones, and even a few that have bi-colored leaves. While there are many ways to classify Japanese maples, leaf color is a valuable way, since color is the reason most people plant this tree.
There are fine examples of red Japanese maple trees, including weeping types, that fall into either the Acer palmatum atropurpureum group or the Acer palmatum dissectum group. The dissectum group is known for their lacy "dissected" leaves. They often display red-colored leaves all summer, which become a brighter red in fall, making them spectacular specimen trees for fall. Suitable for USDA hardiness zones 5 to 8, they should be planted full to partial sun and in a well-drained soil. In zones 7 to 8, they can profit from the respite from the heat by planting them in an area with partial shade or dappled sunlight.
- 'Bloodgood' (Acer palmatum atropurpureum 'Bloodgood'): This is one of the most popular cultivars. It achieves a maximum size of 20 feet tall with a similar spread, making it just the right size for patio landscaping. The leaves of 'Bloodgood' are reddish-purple in summer (but tend to green-up some in full sun). At fall foliage time, the leaves deepen into crimson red.
