Citrus Rootstock – Trifoliata – Seedlings

Trifoliata (Trifoliate Orange or Hardy Orange) is a deciduous member of the citrus family and is generally more cold tolerant than most citrus species. It is recognisable by its three leaflets and long thorns and can often be seen growing from the base of other citrus plants that have been grafted to it.

Its hardiness and resistence to pests and disease make it an obvious choice as a rootstock.

Grown without grafting it will form a shrub up to 6m tall, flowering in spring with fruit ripening in autumn. The fruit is small, full of seeds and very sour.
