Southern Arrowwood, Viburnum dentatum
 
Southern arrowwood is a beautiful shrub with many white, flat-topped flower clusters that bloom in June and produce attractive, bright blue berries. The shrub grows 3-5 m tall.
 
Ecology: 
Southern arrowwood is the larval host plant for the spring azure butterfly. It blooms after the spring ephemerals, and before most prairie plants. Therefore, it is a great nectar source for bees and butterflies in a period when not much blooms.
The berries are a favourite of Northern flickers and many songbirds, as well as small mammals.
 
Growing conditions:
Prefers moist conditions in sun to part sun, but can also grow in shade, drier conditions and sand. It can tolerate brief flooding and is ideal for a spot close to a downspout or in a rain garden.
