    Japanese Maple 'Annie Irene' Overview

    Acer palmatum 'Annie Irene' is an upright deciduous small tree or shrub with leaves that emerge lime green. The foliage then matures to a yellow-green with edges that are flushed red before turning a striking yellow-orange in autumn. Commonly known by the names Japanese Maple 'Annie Irene' or Acer 'Annie Irene', it has insignificant red flowers in spring followed by red-green winged fruits in spring/summer. It likes a sheltered position in partial shade. Leaf colour will be more impressive when grown in a slightly shaded area, but it will tolerate full sun if soil conditions are moist enough. Otherwise, leaf scorch may occur. It prefers soil that is on the acid, rather than the alkaline side, that is moist but well-drained. So keep well watered during dry spells (and regularly water newly planted trees). Additional plant feed may be required for potted or container-grown specimens. Acers can also benefit from spring and/or winter mulching with a helping of ericaceous material such as pine needles or chopped bracken. Little to no pruning is recommended, however removing dead or unwanted branches can be done in late autumn to midwinter. A low-maintenance, architectural plant, Acer palmatum 'Annie Irene' is a welcome addition to many garden styles, including courtyards, rock gardens and Japanese gardens. This cultivar is protected under intellectual property laws by Plant Breeders' Rights. These provide the breeder of new plants exclusive control over the plant material for a set amount of time.
