For the purpose of this page, we are interested only in that group known as Japanese Maples - or Japanese Acers. These normally fall in the group known as Acer palmatum - which is to say that the foliage is generally palm-like. (As in hand rather than palm trees!).
There is another group of the Acers which can rightly claim to be known as Japanese maples. These are those Acers in the Acer japonicum group. (japonicum = of Japanese origin).
Most of the shrubs - in either group - have good autumn colour foliage, and also attractive foliage for growing seasons. All are deciduous.
Foliage colour - Summer and Autumn - is determined to a great extent by the growing conditions regarding soil type and also the weather conditions.
The Acer family of trees - Japanese Maples -and shrubs is a wide ranging group. In terms of size, they can be anything from dwarf shrubs of just under a metre height, to largish trees with a height of 8-10 metres. Either as shrubs or trees, it is the foliage which is the attraction. Often attractive in the spring and summer, but it is the colour in the autumn for which they are really sought after.
Single leaf of Japanese Maple - Acer palmatum 'Dissectum' - showing seven distinct lobes, which are then further divided to put it into the 'Dissectum' group - Acer palmatum 'Dissectum'. This is the early Autumn colour of an otherwise light green leaf on Acer trees.
A point that is overlooked with the Acers group generally, is that there are several types that have variegated foliage. These though do not generally have the same Autumn colour effect as the non-variegated forms.
