The term Dwarf Japanese maple tree does not refer to a specific maple tree species; it is instead used to describe small cultivars derived from the wild Japanese maple tree (Acer palmatum). One of the most well known and popular dwarf cultivars is Acer palmatum 'Beni hime', commonly known as the 'Beni hime' dwarf Japanese maple tree. Despite its growing popularity, this cultivar can still be quite difficult to locate and many ordinary home depots do not include it in their standard collection of cultivars.
The name dwarf Japanese maple tree is sometimes also used for Japanese maple trees kept as bonsai trees. Bonsai trees are however not dwarfed due to genetic reasons; they stay small because they are grown in small containers and often also have their crowns and roots pruned. How much pruning a bonsai tree will receive depends greatly on which bonsai tradition the keeper adhere too. Since the diminutive size is caused by environmental factors, not genetic ones, it is possible to produce a dwarf Japanese maple tree from wild Acer palmatum, as well as from any of the cultivars. This does not mean that all cultivars are frequently used for bonsai creation; some cultivars are more suitable than others.
