Royal Poinciana

Also known as flame or flamboyant tree, Royal Poinciana (Delonix regia) is a semi-evergreen or deciduous member of the bean family characterized by fernlike, lacy green leaves, scores of spoon-shaped, brilliant red flowers and brown pods that make a rattling sound when wind goes through the tree.

Royal Poinciana is a tropical tree that will not thrive if temperatures drop below 45 degrees Fahrenheit. It is a suitable landscape tree for gardeners who can offer it a bright, full-sun location in U.S. Department of Agriculture zones 10 to 12. When grown in proper conditions, Royal Poinciana requires relatively little care.

Royal Poinciana is tolerant of a range of soil conditions, including acidic and alkaline soils, as long as the soil drains well. A location that has some shelter from wind is preferable the tree's weak branches are easily broken. Royal Poinciana may be grown in containers in a warm greenhouse, ideally in a rich, composted soil that is kept moist.Warning: Do not plant Royal Poinciana trees near sidewalks, building foundations, or landscape features such as fountains and statues. The tree's wide-spreading roots can lift and damage such structures. Do not expect to grow anything under the tree, because it will outcompete most plants, including grass, for nutrients. Dropped branches and old seed pods can cause a litter problem, especially in the winter.
