Dogwoods
Cornus sp.

Leaves are opposite simple except for Pagoda dogwood which has alternate leaves.
There are six species of dogwood found in Iowa: Pagoda, Rough-Leaf, Red-Osier, Gray, Round-leaf, and Silky. The dogwoods are used for ornamental plantings in the state, and they make a good shrub row in windbreak plantings. The flowering dogwood, the most popular of the dogwoods, is not found in Iowa, but grows in the eastern United States and west to Illinois.
Dogwoods are rich in tannic acids, and the roots, bark, leaves and unripe fruit were used in early days for medicinal purposes such as tonics and astringents.
Leaves are 3 to 6 inches long. The veins run parallel to the leaf margin.
The mid-vein contains fine strands when pulled apart.
