“Acer palmatum is a deciduous shrub or small tree reaching heights of 6 to 10 m (20 to 33 ft), rarely 16 metres (52 ft), often growing as an understory plant in shady woodlands. It may have multiple trunks joining close to the ground. In habit, it is often shaped like a hemisphere (especially when younger) or takes on a dome-like form, especially when mature. The leaves are 4–12 cm (1 1⁄2–4 3⁄4 in) long and wide, palmately lobed with five, seven, or nine acutely pointed lobes. The flowers are produced in small cymes, the individual flowers with five red or purple sepals and five whitish petals. The fruit is a pair of winged samaras, each samara 2–3 cm (3⁄4–1 1⁄4 in) long with a 6–8 mm (1⁄4–5⁄16 in) seed. The seeds of Acer palmatum and similar species require stratification in order to germinate.
Even in nature, Acer palmatum displays considerable genetic variation, with seedlings from the same parent tree typically showing differences in such traits as leaf size, shape, and color. Overall form of the tree can vary from upright to weeping.
Acer palmatum has been cultivated in Japan for centuries and in temperate areas around the world since the 1800s. The first specimen of the tree reached England in 1820.
When Swedish doctor-botanist Carl Peter Thunberg traveled in Japan late in the eighteenth century, he secreted out drawings of a small tree that would eventually become synonymous with the high art of oriental gardens. He gave it the species name palmatum after the hand-like shape of its leaves, similar to the centuries-old Japanese names kaede and momiji, references to the 'hands' of frogs and babies, respectively.
For centuries Japanese horticulturalists have developed cultivars from maples found in Japan and nearby Korea and China. They are a popular choice for bonsai enthusiasts and have long been a subject in art.
Numerous cultivars are currently available commercially and are a popular item at garden centres and other retail stores in Europe and North America. Red-leafed cultivars are the most popular, followed by cascading green shrubs with deeply dissected leaves.
Preparations from the branches and leaves are used as a treatment in traditional Chinese medicine.
Acer palmatum includes hundreds of named cultivars with a variety forms, colors, leaf types, sizes, and preferred growing conditions. Heights of mature specimens range from 0.5 to 25 m (1 1⁄2 to 82 ft), depending on type. Some tolerate sun, but most prefer part shade, especially in hotter climates. Almost all are adaptable and blend well with companion plants. The trees are particularly suitable for borders and ornamental paths because the root systems are compact and not invasive. Many varieties of Acer palmatum are successfully grown in containers. Trees are prone to die during periods of drought and prefer consistent water conditions; more established trees are less prone to drought. Trees should be mulched with a thick layer of bark. Well-drained soil is essential as they will not survive in soggy waterlogged soil. Trees do not require or appreciate heavy fertilisation and should only be lightly fertilised, preferably using slow-release fertiliser with a 3 to 1 ratio of nitrogen to phosphorus respectively. Nitrogen lawn fertiliser should be avoided in the immediate vicinity of these trees as excessive nitrogen can cause overly vigorous growth that is prone to pathogens.” Information retrieved from Wikipedia 25 July 2018 5:55pm
“The seeds of the Japanese Maple come with a very hard outer coating and if they are not harvested would take about two years to germinate on the ground. A person can improve the odds of germination and shorten the cycle by following certain directions. Once the seeds are picked and the wings have been removed, place them in a bag and store in a cool, dry place until desired. About 100 days before the desired planting date, take the seeds and place them in a container that can withstand hot water. Pour warm to hot water on the seeds and let them soak for around 24 hours. At first most of the seeds will float, but near the 24 hour mark most will have settled to the bottom, then drain off the water. The next thing to do is to place the seeds in a plastic bag with a mixture of sand and peat. It should be moist but not soaking, then poke holes in the bag so there is circulation and finally place the bag in a refrigerator for 100 days. After 100 days the seeds can be planted outside (during the right season).To plant the seeds just sow them on top of a bed of well drained topsoil and cover with approximately 3/8 of soil. Water thoroughly, but allow the soil to dry out completely before watering again. Once they start to germinate they need about 50% shade to keep from sunburn.” Information “Propagation of Japanese Maples by Grant Davison” retrieved from North Dakota State University (NDSU) website 25 July 2018 6:13pm AEST
