Landscape Attributes

Isu Tree is a dense multi-stemmed evergreen shrub with a stunning habit of growth which features almost oriental horizontally-tiered branches. 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 shrub, and usually looks its best without pruning, although it will tolerate pruning. It has no significant negative characteristics.

Isu Tree is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use

Planting & Growing

Isu Tree will grow to be about 4 feet tall at maturity, with a spread of 8 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a slow rate, and under ideal conditions can be expected to live for 50 years or more.

This shrub does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This species is not originally from North America.
