The starfruit grows on a graceful spreading tree that thrives in partial shade. The tree produces flowers and fruits the whole year round in Malaysia. Starfruit trees grown from grafts begin flowering at 9 months while those planted from seed may not flower until they are 4-6 years old.

Starfruit have delicate pink to lavender flowers that are pollinated by honey bees.

Both hot, dry and cold winds can severely damage trees and fruit, so adequate windbreaks are suggested for ideal culture. Give the plant full sun, fertilize 4-5 times a year, and provide moderate water throughout the year. Heavy water during flowering may inhibit pollination and fruit production. Star fruit's are susceptible to root rot under wet conditions, but they generally do well with moderate, year-round rainfall.

The carambola is classified as subtropical because mature trees can tolerate temperatures as low as 27° F for short periods of time with little damage. Like many other subtropicals, however, young plants are more susceptible to frost and can be killed at 32° F. Carambolas can be severely damaged by flooding or prevailing hot, dry winds. The small trees make good container plants.
