Redosier dogwood, Red Osier Dogwood
Cornaceae (Dogwood Family)

with several stems, clusters of small white flowers, and small whitish fruit; rarely a small tree. Height commonly 3-10 feet (0.9-3 m), rarely to 15 feet (4.6 m). Diameter: 3 (7.5 cm).Leaves are opposite.
Red Osier Dogwood is useful for erosion control on stream banks. The common name recalls the resemblance of the reddish twigs to those of some willows called osiers, used in basketry. Branch tips of this tree
will root upon touching the ground.
The genus cornus is Latin for a horn.
