Description and Ethnobotany
Growth Form
It is deciduous in climates with a dry season, shedding its leaves at the end of the wet season.
Crown
Small tree (9 – 15 m tall) with an umbrella-shaped crown.
Trunk
Bark grey and smooth. Short trunk having buttress roots. Branches weak and prone to breakage by wind.
Foliage
Bipinnately compound leaves have alternate leaf arrangement (20 - 60 cm long). Each leaf has 9 - 25 pairs of pinnae; each pinnae consists of 14 - 30 pairs of leaflets.
Flowers
Flowers bright red and orange (10 – 13 cm in diameter). Each flower has 5 similar-sized petals. One of these is a white or light pink standard petal that has red streaks. They have a subtle fragrance.
Fruit
Pods that are initially green and flexible become reddish brown or black, woody and gently curved (30 - 75 cm long, 5 – 8 cm wide) at maturity. Pods each contain 20 – 45 hard, oblong, somewhat flattened seeds (2 cm in length). They split open to release the seeds at maturity.
Habitat
Occurs at altitudes of 0 - 1,000 m and rainfall of 750 - 3,000 mm. It is often found in dry, tropical savannas
Landscaping Features
Landscaping
Often used in parks, gardens and roadsides due to its bright red flowers. Make an excellent shade or focal point tree. It is salt tolerant and may be planted near the coast, but not directly on an open beach. However, the plants sheds numerous twigs, leaves and large woody pods. Shed twigs, leaves and pods may have allelochemicals that inhibit the growth of neighboring plants.

Light Preference
Full Sun, [Remarks] (Delonix regia is light sensitive and trees that grow beside street lamps remain evergreen and do not bloom, or may produce flowers on the side away from the light. )
The coconut palm is a long-lived plant; it has a single trunk, 20-30 meter tall, its bark is smooth and gray, marked by ringed scars left by fallen leaf bases. The tree can live as long as 100 years producing an annual yield of 50 to 100 coconuts. The tree can live as long as 100 years producing an annual yield of 50 to 100 coconuts.
A relatively fast-growing, solitary, slender, unarmed palm which characteristically front the coast in tropical regions and is the allusion of lush, tropical paradises with sandy beaches.
Trunk
Stem tall, slender, grey, prominently ringed with old leaf scars (when the leaf die off, it will fall off cleanly from the trunk, leaving a neat rectangular pattern of circular scars).
Foliage
Fronds pinnate, large, up to 5 m long, yellowish-green to dark green, ascending to spreading to drooping, bearing 80 to 100 pairs of leaflets that taper to a split tip, with prominently elevated midrib; leaflets simple, lanceolate, 1.5 to 5 cm wide, 50 to 150 cm long.
Flowers
Inflorescences spreading, 1.2 to 1.6 m long, cream to yellow, arising from within the lower fronds, consisting of 5 female flowers (with each set between 2 smaller male flowers), enclosed by two bracts (60 to 90 cm long) for protection purposes; inner bract is woody and pointed; male flowers will open about 10 to 20 days to encourage cross-pollination, before the female flowers open.
Fruit
Fruits ovoid, up to 30 cm long, ripening from light green or yellow to brown, consisting of a smooth outer skin (exocarp), a fibrous husk (mesocarp) and a hardy woody shell (endocarp); seed has a narrow, white layer of edible endosperm (flesh) and a large cavity filled with water.
