Acer palmatum is the botanical name of what is commonly called Japanese Maple, a popular plant grown ornamentally in gardens. For those who grow bonsai, the Japanese maple is also a popular choice for a plant.
Japanese maples also come in multiple varieties and as such size, leaf colour and shape can vary. Height, depending on varieties can be 0.5m to 25m tall and growing conditions should be learnt of the specific variety of Japanese maple before obtaining it as growing conditions may be different to as expected.
Aphids can be a problem for this tree along with sunlight. Sunlight itself can be tolerated by several varieties of Japanese maple, but many prefer a bit of shade and generally can grow in complete shade. Slightly alkaline to acidic soils are tolerated, along with clay, loam and sand soils.
