The Averrhoa carambola tree is a relatively short, highly branched slow growing evergreen tree.  Typical star fruit trees can grow up to 9 meters tall. They contains a short-trunk, and white secondary xylem (wood) that will develop a reddish tint over time. Due to all of the branching coming off of the short-trunk, Averrhoa carambola’s  branches appear to form a rounded crown shape. This can be observed in the image located on the right.

The leaves of a star fruit tree are compound, deciduous, and pinnate. They are green in color and alternate sides of the branches while spirally arranging themselves. This spiral arrangement is to insure maximum levels of sunlight is captured. The leaflets themselves are very sensitive to light and abrupt shock. If a tree is shaken, the leaves will curl up together. Also, if observed at night the leaves will be curled up together.




Star fruit tree’s produce a purple streaked flower that are in small clusters at the end of the branches. These purple-streaked flowers for a perfect bell shape with red stalks attaching them to the tree.

This is an image of what a typical star fruit looks like when it is prepared to eat. If you take a cross section of the fruit, it will form the shape of a star. This particular feature of this fruit is where its name, star fruit, originated from.
