Evergreen or deciduous:
The fragrant flowers of star fruit have a pink color and are about 1 cm in diameter. Flowers are borne in clusters in axils of leaves on young branches, or they grow on older branches without leaves. The trees bloom several times throughout the year.
The leaves of star fruit are spirally arranged and 15 to 25 cm long. Leaves have 5 to 11 nearly opposite, ovate-oblong leaflets. These leaflets are 4 to 8 centimeter long. The leaves are soft, medium-green, and smooth on the upper surface. The underside is faintly hairy with a whitish color. The leaflets are sensitive to light and usually fold together at night or when the tree is disturbed.
Carambola fruits are ovate to ellipsoid in shape. They are 6 to 13 cm long and the fruits have 5 (sometimes 4 or 6) longitudinal ribs. The fruit has a golden-yellow to green color. When cut across it shows a 5-pointed star shape, which is why it is also called "star fruit". The crunchy fruits have a slightly tart, acidic, sweet taste. The fruit starts out with a green color. As it ripens the color turns to yellow. The fruit cab be eaten in both the green and yellow stages.
