The kousa dogwood can be distinguished from the closely related Flowering Dogwood (Cornus florida) of eastern North America by its more upright habit, flowering about a month later, and having pointed rather than rounded flower bracts.
The fruit is a globose pink to red compound berry 2–3 cm diameter, though these berries tend to grow larger towards the end of the season and some berry clusters that do not fall from the tree surpass 4 cm. It is edible, a delicious addition to the tree's ornamental value.
Natural germination of dogwood usually occurs in the spring following seedfall, but some seeds do not germinate until the second spring. Germination is epigeal. Stratification of freshly collected seed at 41° F for periods up to 120 days is recommended for overcoming embryo dormancy . After stratification sow in spring (surface) in a light shady spot. Can be transpalnted well, once seedling is a few inch tall.
