The ‘Seiryu’ maple typically grows to a height of 10 to 15 feet (3 to 4.6 meters) with a spread of about 6 to 10 feet (1.8 to 3 meters). Unlike many other Japanese maple varieties, ‘Seiryu’ grows in a more upright and vertical manner, resembling a small tree or shrub with a columnar shape.

This cultivar is highly valued for its versatility and adaptability to various garden settings. Its upright form makes it suitable for smaller spaces, such as courtyards, patios, or even container planting. It can also be used as an accent tree, planted in groups, or incorporated into larger landscapes for vertical interest.
