    Design IdeasShowy and colorful, this is among the best Japanese maple for smaller city yards. Plant in front as a single accent at entries and in foundation beds. Perfectly sized for around outdoor living spaces that ask for shelter and privacy without concern for an overly large tree at maturity. Bold autumn hues provide a long range focal point, particularly against a background of dark evergreen trees. Quintessential tree for the acid garden and among conifers.

    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
    History:
    This species, A. palmatum, may be the most widely bred of the Acer clan. It is credited to Carl Thunberg, 1743-1828, the physician and plant collector working for the Dutch East India Company in Japan. It is likely he collected the first plants, for they were classified after his return to Europe in 1820. Although called Japanese maple, this species is native to China and Korea as well. There are an immense number of cultivars produced by this highly variable species. This form was introduced by Monrovia Nursery Co. Azusa, California in 1998. Its dark red coloring identifies it among the Atropurpureum group, which were first developed from A. p. 'Atropurpureum' after 1857.
    Lore:
    The Japanese maple is the quintessential symbol of fall in the traditional Tea Garden, balanced by flowering cherries for spring.
