Trifoliate Orange

Poncirus trifoliata

Smallish citrus fruit with wrinkled yellow skin and a very sour flavor, similar to a sour orange.

Seed Availability

Seeds are not available for the Trifoliate Orange. Please visit our seed store to view current selections. Seeds were last available in December 2014.


Small to medium sized tree, usually only 10-20ft high. It is an important rootstock for commercial citrus as it provides additional cold hardiness. The Flying Dragon variety (pictured above) is commonly used as a dwarfing rootstock, and when other citrus species are grafted to it, they often grow only 4-8ft high. This rootstock is commonly used for citrus trees found in nurseries. White flowers are followed shortly afterwards by lemon-yellow fruit.


The trifoliate orange is extremely hardy, suriviving temperatures well below 0F.

Growing Environment

The trifoliate orange will defoliate during cold months and needs moderate water during the warm months.


Commonly by seeds.


Fruits are not often eaten, although they are edible, the tree is usually used as an important rootstock for other citrus.
