The 'Arkin' variety represented 98% of the acreage in South Florida in the early 21st century. The carambola tree flowers throughout the year, with main fruiting seasons from April to June and October to December in Malaysia, for example, but fruiting also occurs at other times in some other locales, such as South Florida.  Caramboxin is a neurotoxin which is structurally similar to phenylalanine, and is a glutamatergic agonist.. Iron deficiency (chlorosis) on peach leaves A number of nutritional deficiencies can cause yellow leaves as one of their symptoms, including iron (as you can see above), manganese and zinc. The sour varieties have a higher oxalic acid content than the sweet type.  In Thailand, they are cooked together with shrimp.  Due to concerns over pests and pathogens, however, whole star fruits cannot yet be imported to the US from Malaysia under current United States Department of Agriculture regulations.

Unripe star fruits are firmer and sour, and taste like green apples. , Carambola trees are planted at least 6 m (20 ft) from each other and typically are fertilized three times a year. Like the grapefruit, carambola is considered to be a potent inhibitor of seven cytochrome P450 isoforms. Sometimes the fertilizers used in trees also contain herbicides that cause foliage to yellow and thicken. , Ripe carambolas may also be used in cooking. The fourth reason for yellow leaves is because of a virus disease, such as apple mosaic virus as you can see in this leaf.
