The bush lemon: the knobbly old lemon that went wild

Knobbly golden bush lemons ripening on the tree

If you've ever driven the back roads of the Mid North Coast, you've probably passed a bush lemon tree without giving it a second look. It's usually leaning over an old fence line, or tangled up at the edge of a creek, covered in thorns and fat, knobbly fruit glowing yellow to orange. Nobody's watering it. Nobody's pruning it. It's just... there. And honestly? We think it's one of the best lemons going.

Lumpy, thorny, and nobody planted it on purpose.

So what actually is a bush lemon?

Here's the funny thing: it's not really a "proper" lemon at all. A bush lemon is what botanists call a rough lemon, a natural cross between a mandarin and a citron (one of the oldest citrus fruits around).

It's not native, either. When settlers planted citrus orchards, they often grew their nice, smooth lemons grafted onto tough rough-lemon roots, because those roots could handle just about anything. Years later, when the old orchards were forgotten and the grafted tops gave up, the hardy rootstock kept going. It sent up its own branches, set its own fruit, and quietly went wild.

That's why you'll find bush lemons scattered all along the east coast of NSW and Queensland: on old farms, along creeks and on the edges of the rainforest. Every one is a little piece of local history.

Ugly on the outside, gorgeous on the inside

Let's be honest, a bush lemon won't win any beauty contests. It's lumpy, it's often lopsided, and when you cut it open you'll find a thick rind and not a lot of juice.

But scratch that bumpy skin and smell it. That thick rind is packed with fragrant oils, so the zest is far more intense than a supermarket lemon. That's exactly what makes it so good for cooking.

Marmalade: all that thick peel is perfect for it, and it gives a beautiful bittersweet flavour.
Lemon salt: the zest carries its aroma right through the salt, so every pinch tastes like sunshine.
Cordials and syrups: a few lemons go a long way.

Our tip if you find a tree

Pick them when they're properly ripe, deep yellow to orange, and give slightly when you squeeze them. Grate the zest before you juice them (you'll want every bit of it), and watch out for the thorns. They're serious.

And if you don't have a bush lemon tree handy? Don't worry, we've bottled a bit of ours for you.
