Kousa Dogwood (Cornus kousa)
The kousa dogwood grows as a small flowering tree or a large multi-stemmed shrub. In the summer, the tree is covered in large white flowers that lay flat on top of the leaves. Each flower has 4 pointed petals. The tree's leaves are dark green, oval shaped, and also pointed. The bark has a mosaic-like look, with patches of gray, tan, and brown. This tree also produces bright red raspberry-looking fruits, which although are edible to humans, are usually left to the birds. This tree also attracts butterflies.
