Hardy Orange Tree (Citrus trifoliata / Poncirus trifoliata) Fruit Tree White Flower Seeds

The Hardy Orange Tree (Poncirus trifoliata / Citrus trifoliata) is a unique, cold-hardy citrus species admired for its fragrant white blossoms, glossy trifoliate leaves, and small orange fruits. Unlike traditional citrus, it can thrive in cooler regions, making it a favorite for ornamental and edible landscaping.

These non-GMO hardy orange seeds produce small, thorny deciduous trees that bloom in spring with fragrant white flowers and bear golden-orange fruits in fall. The fruit is tart but edible, often used for marmalade, flavoring, or ornamental display.
