Royal Poinciana (Delonix regia)
Location: Kohala Coast, Big Island, Hawaii
Last year I posted a photo of an immature green seed pod on one of our Royal Poinciana trees. The immature seed pods are green and soft, but as they ripen, they become brown and hard. Today's photo shows a mature Royal Poinciana seed pod.
Eventually the pods will drop from the trees onto the ground, unless they are removed ahead of time. If you pick up and shake one of these mature seed pods, you will hear the seeds inside rattle against the hard shell of the pod. The seed pods are are between 12 and 18 inches long (about 30 to 45 cm). Seed pods like this are characteristic of trees in this family (Fabaceae).
