The Carambola is a beautiful evergreen tree with delicate small pinnate foliage that is sensitive to light-folding up in low light. Known for its increasingly popular yellow skinned "Star fruit" which is star like in appearance when it is sliced. This tree grows very well indoors with warmth and bright light.
Carambolas are best consumed when ripe, when they are yellow with a light shade of green. It will also have brown ridges at the five edges and feel firm. An overripe fruit will be yellow with brown spots. The fruit is entirely edible, including the slightly waxy skin. It is sweet without being overwhelming and extremely juicy. The taste is difficult to compare, but it has been likened to a mix of papaya, orange and grapefruit all at once.
Carambola is rich in antioxidants and vitamin C and low in sugar, sodium and acid. It is also a potent source of both primary and secondary polyphenolic antioxidants.
Best grown outside in zone 9A and above, although we have grown it in zone 8B. Also can be grown in warm greenhouses.
