Design IdeasThe more diminutive Japanese maples become a most valuable small trees for home landscapes. No other tree conveys the Asian or Japanese garden character to a landscape whether traditional or a spare zen-like modern design. But these maples also belong in natural groves of much larger trees because the shelter of high canopies ensure they attain their richest foliage hues. Their preference for acidic soils also make them perfectly adapted to grow within the influence of needled evergreens. Smaller stature is excellent for foundation beds because they won't crowd windows. Excellent for small scale naturalistic drifts of landscape.

Companion PlantsVivid lime green foliage of this Japanese maple and its smaller stature deserve to be grouped with bold contrasts from black leaf Ebony Knight Mondo Grass, (Ophiopogon plansicapus 'Ebknizam'), Purple Petticoats Coral Bells, (Heuchera x 'Purple Petticoats') and Burgundy Lace Painted Fern, (Athyrium nipponicum 'Burgundy Lace'). This is a fine cultivar for Japanese garden compositions with Shugetsu Azalea, (Azalea satsuki 'Shugetsu'), White Striped Dwarf Bamboo, (Sasella masumuneana albostriata) and Dwarf Mugo Pine, (Pinus mugo pumilio).
This species may be the most widely bred of the entire Acer clan. First A. palmatum plants are credited to Carl Thunberg who classified them after his return to Europe from Japan in 1820. Although called Japanese maple, the species is native to China and Korea as well. It's dark red coloring identifies this plant among the Atropurpureum group, first developed when breeding in the west began after 1857. But in Asia breeding dates back centuries. This dissectum form originated in the 18th century and represents a subspecies with Seiryu among the most upright of all forms.
This maple and its cultivars are essentials of the Japanese tea gardens. Its vivid leaves are considered to be the flowers of autumn. Maple is balanced in spring with the flowering cherries, which together are the quintessential symbols of seasonal cha
