Acer palmatum Kagiri-nishiki - Japanese Maple

The Acer palmatum 'Kagiri-nishiki', also called Acer palmatum var. roseomarginatum, is a superb variety of variegated Japanese maple. Its delicate leaves are finely cut and toothed, twisted, with a slightly bluish-green colour. They are edged with pink-white in spring and white in summer. In autumn, the foliage turns a beautiful pink-red to orange and retains its variegation. The bush has a rounded habit and modest size. Give it a prominent place, visible from the house or in a pot on a non-scorching patio.

Originating from eastern China, Korea, and Japan, the Acer palmatum is the source of numerous horticultural varieties that compete in beauty. The Japanese maple, like all maples, belongs to the Aceraceae family. It is relatively hardy but only tolerates limestone-free soils.

The 'Kagiri-nishiki' cultivar develops a spreading to rounded habit over time. It reaches 1m (3ft) in height and 1.5m (5ft) in width at 10 years old. Eventually, it reaches a height and width of 3m (10ft). This small tree has a brown to reddish bark and develops magnificent deciduous leaves, finely cut into palm-shaped lobes, divided into 5 to 7 ovate and acuminate lobes, each slightly different in shape. The foliage is bluish-green with pink and white margins in spring, loses the pink in summer, and becomes pink-red in autumn before falling, retaining its variegation. The leaves are opposite, 5 to 10cm (2 to 4in) long, and quite twisted. The inconspicuous flowering occurs in May or June. The purple flowers are grouped in small clusters and sometimes produce fruits with recurved wings, called samaras, 3cm (1in) long.

The Acer palmatum 'Kagiri-nishiki' thrives in sunny, non-scorching locations or partial shade, sheltered from cold, dry winds. It appreciates acidic, moist, fertile, loose, and well-drained soil. Its beautiful appearance makes it compact and suitable for small gardens ornamenting terraces and shady rockeries. Enhance its varied colours with low-growing perennials such as Heucheras with pink-coloured foliage, green Ophiopogons, and small blue Hostas. Add acid-loving plants such as wild camellias, heathers, and small azaleas in flower beds. Plant it alone or combine multiple varieties of Japanese maples to create a lively and vibrant colour palette.

Tip: Treat with fungicide to prevent Verticillium attacks.
