Red-Osier Dogwood is a distinctive bush year-round: Its maroon stems stand out in winter snows; its clusters of numerous, tiny white flowers are showy in the spring and summer; its white fruits are handsome all summer long (but don't last long because birds enjoy them); and its leaves are an attractive maroon in the fall.

Red-Osier Dogwood grows to about eight feet tall and spreads into a thicket by sending out root shoots.  Before its leaves are on, Red-Osier is sometimes mistaken for a willow.

Linnaeus named both the genus and the species in 1771.  Recent research confirms that the North American species is the same as the European species and is, therefore, to be named the same: Cornus alba.

"Cornus mas" was a Latin name for the Cornelian Cherry tree; "corn" is Latin for "horn", referring to the dense wood. "Swida" is the common Czech name for the plant and "sericea" is Greek for "silken".
