Viburnum alnifolium
Hobblebush

Identification

- Sprawling shrub, 3 to 8 feet.
- Leaves large (4 to 8 inches), opposite, heart-shaped, rough surface, finely toothed edge.
- Saucer-sized clusters of many white flowers. 
- Large flowers (sterile) surround tiny inner flowers (fertile).  
- Clusters of red to deep-blue berries form in Aug-Oct.

Flowering  Are some or all of the plant (s)...


   Before flower
- The tiny white flowers are not yet open.

   In flower -
The tiny white flowers are open enough to allow access to a pollinator, but not all petals have wilted or dropped.

   Past flower
-
Petals have wilted or dropped.  The remaining small whitish-yellow ovaries will begin to grow into green fruits

 
Fruiting  Are some or all of the plant(s)...


   Before ripe fruit
- The fruits have not turned deep-blue.  Clusters of the fruits are initially green.  While they develop, they will first turn red before they eventually ripen and become deep-blue.

   Ripe fruit
The fruits have turned from red to deep-blue.

   After ripe fruit
- We are not monitoring this stage for this spcies.  Because not all flowers will develop into fruits, it is difficult to determine if a “missing” fruit at the end of an empty stem is the result of fruit that already fully ripened and dispersed, or the result of a flower that was not pollinated and therefore never began to develop into a fruit.
