The tree tomato is a member of the nightshade family (Solanaceae). The regular tomato belongs to the same plant family but is a different species. The tree tomato has the scientific name Cyphomandra betacea. Like the true tomato, it is a native of Peru. It is grown in market gardens there and in several subtropical countries, including Brazil and New Zealand.
The tree tomato is woody, grows from 8 to 10 feet tall, bears fruit two years after seeding, and may continue to bear for five to six years. They are not winter hardy except in southern areas and need to be taken inside during winter. Fruits of the tree tomato are oval, about 2 inches long, and change from greenish purple to reddish purple when fully ripe. The fruits are low in acid and the flavor is moderately agreeable. Some varieties of the tree tomato produce bright, red fruits. The fruits can be used in stew or preserves after the tough skin and hard seeds are removed.
