Landscape Attributes

Ryu Sei Japanese Maple is a multi-stemmed deciduous shrub with a rounded form and gracefully weeping branches. 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.

Ryu Sei Japanese Maple is recommended for the following landscape applications;

  • Accent
  • Hedges/Screening
  • General Garden Use
  • Groundcover
  • Container Planting

Planting & Growing

Ryu Sei Japanese Maple will grow to be about 4 feet tall at maturity, with a spread of 6 feet. It has a low canopy. 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.

Ryu Sei 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.
