I have seen a few of these this year, having somehow never noticed them before:
The Kousa dogwood (Cornus kousa or Benthamidia kousa) is a small deciduous tree 8–12 m (26–39 ft) tall, native to Korea, much of China, Japan, Korea, Taiwan, Sikkim, Bhutan and the Ryukyu Islands. It is also reportedly naturalized in Hawaii, Connecticut and New York State. It is widely cultivated as an ornamental.
The fruit is a globose pink to red compound berry 2–3 cm in 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 sweet and delicious addition to the tree’s ornamental value. The fruit is sometimes used for making wine.
