A compact and round dwarf variety with graceful soft red foliage in spring that darkens to burgundy in summer; fall color brightens to sunset hues of crimson and orange; excellent as a small garden accent
Oregon Sunset Japanese Maple has attractive burgundy foliage which emerges red in spring. The lobed palmate leaves are highly ornamental and turn outstanding shades of gold, orange and crimson in the fall. Neither the flowers nor the fruit are ornamentally significant.
Oregon Sunset Japanese Maple is a deciduous tree with a strong central leader and a more or less rounded form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.
This is a relatively low maintenance tree, 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.
Oregon Sunset Japanese Maple is recommended for the following landscape applications;
Planting & Growing
Oregon Sunset Japanese Maple will grow to be about 4 feet tall at maturity, with a spread of 4 feet. It tends to be a little leggy, with a typical clearance of 1 foot from the ground. It grows at a slow rate, and under ideal conditions can be expected to live for 60 years or more.
This tree 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.
Oregon Sunset Japanese Maple is a fine choice for the yard, but it is also a good selection for planting 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. It is even sizeable enough that it can be grown alone in a suitable container. 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.
