The '''Kousa Dogwood''' (''Cornus kousa'' or ''Benthamidia kousa''), also known as the '''Japanese Flowering Dogwood''' ({{Nihongo|Yamaboushi|ヤマボウシ|Yamaboushi}} in Japanese), is a small [[deciduous]] [[tree]] 8-12 m tall, native to eastern [[Asia]]. Like most [[dogwood]]s, it has opposite, simple [[leaf|leaves]], which are 4-10 cm long.
The tree is extremely showy when in [[flower]], but the "flowers" are actually showy white [[bract]]s below the cluster of inconspicuous yellow-green flowers. The flowering is in spring, shortly after it leafs out. It has a relatively upright habit, unlike the closely related [[Flowering Dogwood]] (''Cornus florida'') of eastern [[North America]], which has a sprawling habit. It also differs from that in flowering about a month later, and in having pointed (not 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 berries that do not fall from the tree surpass 4 cm. It is edible, though lacking any interesting flavour.
There are two [[variety (biology)|varieties]]:
*''Cornus kousa'' var. ''kousa''. Leaves 4-7 cm; flower bracts 3-5 cm. Japan.
*''Cornus kousa'' var. ''chinensis''. Leaves 5-10 cm; flower bracts 4-6 cm. China.
It is resistant to the dogwood [[anthracnose]] [[disease]], caused by the fungus ''Discula destructiva'', unlike Flowering Dogwood, which is very susceptible and commonly killed by it; for this reason, Kousa Dogwood is being widely planted as an ornamental tree in areas affected by the disease. A number of [[hybrid]]s between Kousa Dogwood and Flowering Dogwood have also been selected for their disease resistance and good flower appearance.
