A flower and leaves of katmon

Flowers white, large, showy, about 13-16 cm wide.

Fruit  rounded, 5-6 cm in dia, edible, pulp fleshy, green.


Katmon  fruits are eaten and taste somewhat like green green sour apples. Fresh fruit is not particularly good but, owing to its acid, juicy character, it is refreshing when eaten in the woods. It makes an excellent sauce or jam and is also used for flavoring fish.

A red dye is obtained from the bark of this tree.

The sourish juice of katmon fruits, when mixed with sugar, is used as a cough cure.  It is also employed for cleaning the hair.


Katmon is quite sensitive to cold and should not be planted at locations where the minimum temperature can reach 10 C.  The tree seem to require locations which recive enough sunlight.

            New trees can be raised from seed.
