    Design IdeasThe smaller size of Japanese maples, and when they bear season long foliage color become a most valuable tree 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 around homes and in naturalistic drifts of landscape. They are ideal for urban gardens where plants are protected by buildings from wind and sun. Maples even do well in large containers for porch, patio or terrace.

  • Care
    Care Information
    Thrives in well-drained soils with neutral to acidic pH. Water deeply and regularly during the first few growing seasons to establish an extensive root system. Reduce frequency, once established. To keep roots cool and preserve moisture, apply a thick layer of mulch, avoiding the trunk. Shelter from harsh, drying winds. Apply fertilizer in spring.Pruning time: winter.
    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    A mutation or sport of A. palmatum 'Bloodgood' discovered at Greer Gardens in Eugene, Oregon. Introduced in 1988. 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 began after 1857. The maple family Aceraceaeholds just two genera named from the old European name for maples. There are about 200 species from northern temperate rergions around the world.
    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
