Fruits of Malayan kumquat
Malayan kumquat grows well in tropical and subtropical areas. However, it is cold sensitive and cannot be planted in frost prone areas. In such areas the trees should be planted at protected spots.
These plants are quite ornamental due to their small bright yellow fruits. So these are mostly planted as ornamental plants in gardens and as a roadside shrub. Malayan kumquat is also a popular potted plant too and many nurseries sell it as a potted plant only. It is also sometimes made into a hedge.
Malayan kumquat is usually propagated from seed. However, air layering is also feasible and often practiced by nurseries for adding value to their plants.
