Purple Leaved Japanese Maple A small deciduous tree that has been in cultivation in Japan for a very long time. The fresh, delicate looking foliage is almost transparent in the sunlight and the overall shape of Japanese Maples make them an excellent choice as a specimen tree in a sheltered spot. Acer palmatum Atropurpureum is the dark purple-leaved form of the common Japanese maple with exceptionally great Autumn colour.Growing notes:Acer palmatum and its cultivars are slow growing and do not really require pruning, but will tolerate it if necessary - remove damaged, diseased or crossing branches - it is best done during the dormant months. Lower branches can be taken off to shape the canopy over time. Japanese maples all require shelter from wind to avoid wind scorch. The very fine leaved cultivars need extra protection from wind and the sun. Despite being hardy, the fresh growth can be vulnerable to frost in the Spring. They all tolerate growing in a large container, some for a very long time. Cultivars with green or yellow foliage are best grown in dappled shade as full sun can scorch the leaves. Cultivars with purple or red foliage require some sun to fully develop their dark colour. Cultivars with variegated foliage require shade from the afternoon sun to prevent scorching.
