Royal Poinciana (Delonix regia)
Location: Kohala Coast, Big Island, Hawaii
Seed pods are sprouting on the Royal Poinciana trees in my garden. The new seed pods, which resemble long green beans, are between 12 and 18 inches long (about 30 to 45 cm). The pods are green and soft right now, but later they will harden and turn brown as the seeds inside mature.
This is the latest photo documenting the seasonal stages of the Royal Poinciana. In May I posted a photo of buds on a branch of one of the trees. In July I posted a photo of a single Royal Poinciana blossom, and another of a mass of blossoms on the same tree. Later, I'll post a photo of the mature brown seed pods -- but as of today, the pods are green.
UPDATE: Here is a photo of a mature Royal Poinicana seed pod.
