Kou (Cordia subcordata) is an indigenous tree that was also brought over by Polynesian settlers. It was highly prized for its wood, which was used to make bowls and other containers.
The flowers are beautiful, too. Less than two inches across, they grow in clumps, which are sometimes hidden by the shiny green leaves. The flowers are followed by small, round green fruits (seen in the photos to the left and below) which harden to a dark brown and contain white seeds.
The flowers on this tree were popular with a variety of insects including a honey bee, above, and a paper wasp (Polistes exclamans), below.
