Maroon fall foliage; alternate leaves which is unusual for a dogwood.  The branches are parallel to the ground creating a layered tiered look with upturned branches like a pagoda.  It has a fibrous, spreading root system and prefers when the root zone is kept cool.  Plant in moist, acidic soils, in the shade but will grow in the sun.  It does not transplant well due to its shallow root system.  Can be grown as a small tree or large shrub reaching heights of 30'.
