royal poinciana, Delonix regia

One of our world's greatest flowering trees? Only barely a wildflower. Royal poinciana is a Madagascar native, endangered at home. But now it'd flourishing around the world, and spread to the wild a little in Florida and Hawaii. Sometimes the flowers are more red, sometimes more yellow, and sometimes fade to more red as they age. Always just about as colorful as you can get! Krohn Conservatory, Cincinnati OH, 7/14/15.
