10 Seeds to Grow of The Flame Tree is also called Royal Poinciana, fire tree or flamboyant tree. It is a tropical tree species from the legume family which produces large, fiery red or golden flowers that blossom from spring through summer. The seed pods can grow 30 – 60 cm (12 to 24 inch) long and will look out of proportion on a bonsai tree if you let them develop. The leaves are pinnately twofold and remind of fern leaves. The bark is greyish-brown, smooth on young trees and becomes rough with age. The tree grows fast, can become 10 meters (33ft) high and it takes on a natural umbrella shape which should also be aimed at when the flame tree is styled as a bonsai. In tropical climate the tree is more or less evergreen while in cooler subtropical regions it will be deciduous. The flame tree does not tolerate frost and needs temperatures between 50° F / 10° C and 68° F / 20° C in winter.
