If you are visiting in late June, you will likely see the Sea Bilberry (Vaccinium bracteatum) in full bloom, covered in rows of tiny, white, bell-shaped flowers. This unique shrub is in the same family as the azaleas for which Unzen is famous, although this particular plant is more closely related to cranberries and blueberries. Like its cousins, in autumn the Sea Bilberry produces dark purple berries that are edible.
