How to Grow Acer palmatum Atropurpureum Plants in your Garden

Gardener's HQ Guide to Growing Purple Japanese Maple

Acer palmatum atropurpureum, or Japanese Maple, is a small deciduous tree of the Aceraceae family.

It has vibrant reddish-purple palmate leaves that turn a striking crimson red in the autumn / fall.

This tree is able to hold onto its red and purple hues quite well throughout the summer.

These brilliant colours are the main reason that many people decide to grow this tree, even though it can be picky about its location in the garden.

It makes a lovely accent piece in a small area, or as a contrast against other tree foliage.

Another ideal location to place this tree is under a canopy of taller trees, as it prefers afternoon shade and filtered light. Or perhaps plant it near Hydrangeas or azaleas because it also prefers slightly acidic soil conditions.

For successful growth, Japanese Maple needs just the right amount of light; too little light in some varieties causes leaves to turn greenish, whereas too much light can damage the leaves through scorching.
