Momordica balsamina


Momordica balsamina is a tendril-bearing annual vine native to the tropical regions of Africa, introduced and invasive in Asia, Australia, and Central America. It has pale yellow, deeply veined flowers and round, somewhat warty, bright orange fruits, or "apples". When ripe, the fruits burst apart, revealing numerous seeds covered with a brilliant scarlet, extremely sticky coating. The balsam apple was introduced into Europe by 1568 and was used medicinally to treat wounds. In 1810, Thomas Jefferson planted this vine in his flower borders at Monticello along with larkspur, poppies, and nutmeg.
Some people indicated that the outer rind and the seeds of the fruit are poisonous, however the Tsonga people found in the northern region of southern Africa eat the leaves of the plant along with the fruit which bears its name.
