In my great pursuit of finding cold hardy citrus to grow in my north texas food forrest I was lucky enough to be gifted a calamondin citrus tree from a friend ‪@urbanharvestdfw‬ Although, this is not a calamondin citrus tree, as he thought! But what is it??

🍊 Meet the Trifoliate Orange: Nature’s Coolest Citrus Rebel! 🌿

Not your average orange tree, this thorny wonder can survive temperatures that would make other citrus trees shiver! Native to East Asia, the Poncirus trifoliata is like the tough guy of the citrus world - cold-hardy, drop-dead gorgeous, and totally unique.

Three-leaved, super spiky, and sporting the most adorable white blossoms in spring.

Pro tip: Don’t try to eat its fruits unless you’re into extreme sourness! 😂 Perfect for gardeners who love something a little different. It will probably be great cooked or made into a marinade or cocktail.
