Often called the most beautiful flowering tree in the world, royal poinciana fills its spreading, handsome branches with feathery foliage and flamboyant scarlet-orange blossoms in late spring and early summer. A semi-deciduous tree native to the island of Madagascar, it is drought and salt-tolerant, making it among the quintessential trees for tropical landscapes, rivaled for its fame only by the coconut palm.
Typically without leaves in the dry winter months, the tree buds with the return of warmth and summer rains. The foliage is feathery and finely textured, with bright-green, doubly pinnate leaves – as many as 1000 leaflets making up one of the leaves. Simultaneously with or prior to the emergence of new leaves, the branches blaze with masses of large orange-red flowers with four mushroom-shaped petals and one more that is slightly larger and often speckled with dots of another color. When in bloom, the mounded canopy can be a solid cloud of red, orange or yellow-orange. Large seed pods follow the flowers, which are pollinated by insects and birds.
Royal poinciana's wood is considered brittle and can readily break in strong windstorms, and is seemingly favored by termites. Use this “beyond beautiful” tree as a seaside specimen or space-requiring street tree near the beach or inland. It may also be trained as a bonsai. The natural variety flava is scarce but has golden yellow flowers with the fifth petal marked in red and white. (info source: Learn2Grow.com)

|Germination||1. Boil water and put the seeds in to it. After a couple of minutes add cold water until the temperature drops to 110 degres F (45 C): the water should feel very hot but not burning. Leave the seeds in the water overnight. After 24 hours the membrane covering the seeds peels by itself. 2. Put in moist motting soil and wait 1-2 weeks for seedlings to show.|
3. Lightly cover the seeded area with mulch to reduce soil compaction in sun and rain. Water shallow seed lightly and frequently until they sprout. Water deeper seeds slowly and deeply, but do not keep wet or they can rot. When seeds sprout, encourage deep roots by gradually reducing watering frequency and increasing the amount, to get it down deep around and below roots while letting soil surface dry between soakings.
