Plant Profile: Acer palmatum

The Japanese maple, a compact tree belonging to the Sapindaceae family, originates from southeastern Korea and central to southern Japan. It is celebrated for its numerous visually appealing varieties, which include both weeping and upright forms. This species is particularly renowned for its striking deep red and orange foliage during the summer, which intensifies as autumn approaches. (For weeping varieties, refer to Acer palmatum 'dissectum.')

The leaves of the Japanese maple measure between 2 to 5 inches, are arranged oppositely, and are simple with five to nine lobes, most of which are deeply divided. Their color transitions from green in the summer to shades of yellow, bronze, purple, and red in the fall, depending on the cultivar. This tree is highly valued as a specimen plant and is one of the more adaptable maple species for landscaping. However, the young leaves are susceptible to frost, and the tree does not tolerate drought well. Most cultivars are grafted and can be cultivated as either single or multi-stemmed small trees. They may experience leaf scorch if exposed to excessive sunlight, wind, or drought conditions. Additionally, this tree has a mild resistance to deer damage.

The growth rate of the Japanese maple is slow to moderate, and it develops a layered appearance with a low, dense, rounded canopy and spreading branches. Its texture ranges from medium to fine. It thrives best in dappled shade and requires evenly moist, well-drained soil, while also needing protection from drying winds.
