Flower DescriptionFlowers are white to pale pink, held in pairs and are about 5 cm in size. The plant is self fertile however yields are improved with cross-pollination.
Fruit DescriptionThe fruit is pear-shaped, somewhat tomentose during its immature stage but when fully developed they are 8-12 cm long and 6-10 cm wide. They are frequently used in making jams and jellies since they have a high pectin content, however they are usually too hard, sour and astringent to eat fresh from the tree.
