This is a very attractive shrubby tree that can look great in the garden.
It has showy white (sometimes pink or red depending on the cultivar) bracts that can reach about 5 inches (12 cm) in diameter in the spring and early summer.
This shrub also brings colour into the garden in the autumn, when its dark green oval leaves turn to a reddish purple color.
Some varieties also bring interest to the garden in the winter as they have attractive stems; unfortunately these cultivars do not tend to have comparable showy attractive bracts as other common Cornus kousa cultivars come the spring.
It is also a great plant to grow to attract birds into your garden, though you may prefer to eat the Kousa dogwood fruit yourself as opposed to letting our feathered friends have the joy of eating them all.
The flowers are very showy making this a great ornamental plant to grow in the garden, especially for those who are also into making unusual jams from fruits that are more often left for birds and other animals to consume.
The fruits are spherical and are an oft eaten wild berry (See Dogwood Jam recipe (in Miscellaneous) for further details. It is usual to discard the rind (bitter tasting) and seeds.
