One of the best Japanese maples for autumn colour, Acer palmatum 'Osakazuki' is an elegant plant with leaves which turn glorious shades of bright scarlet in the autumn. The leaves are lush and dark green from spring to early autumn.
A superb large garden shrub or small tree for leaf colour in October. Acer palmatum 'Osakazuki' is ideal for border planting and will also grow well in a large pot or container for many years.

Like all Japanese maples, Acer palmatum 'Osakazuki' prefers a situation sheltered from the most severe winds. It is more sun tolerant than some maples but appreciates a little shade if possible.
The literal translation of 'Osakazuki' is “saki-cup-like”, referring to the way that the leaves of this cultivar sometimes “cup” at their base.
Although Acer palmatum is usually known as the Japanese maple, it actually also grows in Korea and right across China into Sichuan Province in the west.
The autumn colours of many maples, especially selections of Acer palmatum is very dependent on the pH (acidity / alkalinity) of the soil. They prefer lime free soil, so here, on our almost neutral ground, we are applying an annual dressing of sulphur granules round our maples at the rate of 1 or 2 oz per square yard, to make the soil more acid, and year by year the intensity of the autumn colour increases.
