These bracts show up at the spring and last for about six weeks since the tree leafs out, eventually turning pink with age till they drop off.
From the late summer or early fall, kousa sprouts pink edible fruits. They’re bumpy-looking berries around 1/2 inch in diameter. Once mature, they aren’t too bad. (Could you tell they’re not my personal favorite?)
As they ripen, they make more pink, turning into a dark cherry shade. These berries are the easiest way to differentiate kousa from other dogwood species.
From the fall, kousa dogwood’s leaves turn a brilliant reddish-purple. In the winter, the absence of leaves reveals lovely bark that exfoliates with age, which is just another distinctive trait.
How to utilize it. Kousa dogwood is a wonderful ornamental tree to your lawn. Use it as a specimen tree or in a grove. Because it is tolerant of shade, you might also use it at the edge of a woodland.
If you would like to maintain your dogwood’s flowering season going as long as possible, utilize it with flowering dogwoods, as kousas will bloom about a month later than flowering dogwoods.

Dig a hole twice as wide and as deep as the root ball. Loosen up its roots and place it in the pit. Fill the remainder of the hole back with soil and tamp it down.
