A stunning small tree with outstanding orange-yellow spring color that is very bright; green in summer but puts on a spectacular display of yellow and orange in the fall; vigorous and upright growing; a fine garden accent
Ueno Yama Japanese Maple has attractive green foliage which emerges yellow in spring. The lobed palmate leaves are highly ornamental and turn outstanding shades of yellow, orange and red in the fall. Neither the flowers nor the fruit are ornamentally significant.
Ueno Yama Japanese Maple is a deciduous tree with a strong central leader and a shapely oval 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.
Ueno Yama Japanese Maple is recommended for the following landscape applications;
- Mass Planting
- General Garden Use
- Container Planting
Planting & Growing
Ueno Yama Japanese Maple will grow to be about 15 feet tall at maturity, with a spread of 10 feet. It tends to be a little leggy, 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 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.
Ueno Yama 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. 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.
