The lovely leaves of this slow growing variety emerge bright pink in spring, changing to soft green or yellow-green in summer, then turning red in fall; coral bark and branches become visible in winter; an ideal selection for gardens or containers
Corallinum Japanese Maple has attractive light green foliage with hints of chartreuse which emerges pink in spring. The lobed palmate leaves are highly ornamental and turn an outstanding red in the fall. Neither the flowers nor the fruit are ornamentally significant. The rough coral-pink bark and pink branches are extremely showy and add significant winter interest.
Corallinum Japanese Maple is a dense multi-stemmed deciduous shrub with a mounded form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.
This is a relatively low maintenance shrub, and should only be pruned in summer after the leaves have fully developed, as it may 'bleed' sap if pruned in late winter or early spring. It has no significant negative characteristics.
Corallinum Japanese Maple is recommended for the following landscape applications;
Planting & Growing
Corallinum Japanese Maple will grow to be about 10 feet tall at maturity, with a spread of 7 feet. It has a low canopy with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 60 years or more.
This shrub does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
Corallinum Japanese Maple makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
