Abiu Tree

Medium to a large tree in tropical areas with a pyramidal or oval canopy. The secondary and tertiary branches that emerge from the main limbs are generally willow-like (thin and long) and hang

downward when heavy with fruit. The tree tends to have a smaller canopy that attains a height of 12-15ft and spreads to a width of 15-20ft. The fruits are borne partly along their leaf axis and on the terminal ends and almost take 120 days from flower to ripened fruit. The tree starts flowering from its second years onwards even though they are not vegetative propagated. Ideal for both commercial and homestead painting.

The flowers are borne singly or in clusters of 2–5 flowers in leaf axils on long, thin shoots. Flowers are hermaphroditic, small, 4- to 5-lobed, cylindrical, and white to greenish. Flowers open during the morning and may stay open for about 2 days.
