Palmatum f. atropurpureum, and A. palmatum f. linearilobum. Because taxonomists are attempting to show evolutionary relationships between the different taxa, as reflected in the variations between natural populations, it added to the confusion to name species and infraspecific forms from cultivated plants. For instance, Acer dissectum, A. ornatum, and A. palmatum var. heptalobum were based on Japanese garden plants. Modern taxonomic techniques, including chemical analysis, have indicated all these plants, in spite of large visible morphological differences, have the same fun- taxonomy and nomenclature damental characters and can be placed under the one species, Acer palmatum.
The site must be reasonably well drained. Japanese maples do not do well in a wet or swampy location, but they may be grown along pools and little streams provided the root zones have sufficient drainage and aeration. I have seen these plants growing on dry hillside locations in a clay soil and under a hot sun. Although their annual growth was limited and certainly could not be called lush, at least the plants were fine small trees fulfilling a particular need. The roots of Japanese maples are not deep, so mulching is also important in tight, heavy soils.
Not only can the dwarf Many dwarf cultivars, such as ‘Kamagata’ shown here, work well in alpine plantings. Photo courtesy of Oregon State University Archives, Corvallis culture forms be utilized singly or in small groupings, but the larger-growing dissectums and the upright cultivars also do extremely well. The choices of form, color, leaf texture, and winter branching are wide-ranging. The full-sized types, including the species, grow well in tubs or large permanent containers. Occasional directive shaping or pruning is not a demanding chore, attention possibly once or twice a season being required.
