Rough Lemon – A Rare and Unique Citrus

Have you ever heard of Rough Lemon? I hadn’t either until one of my organic small farmer friends said she had some lemons for our Harvest2U customers. I asked what the variety was, and she said she didn’t know. I asked her to send me a picture, and when I saw it, I doubted very much that it was a lemon but rather some form of a mutant orange.

After doing research, I identified this curious looking citrus as a Rough Lemon. Rough Lemon (Citrus jambhiri) is the fruit and the tree of a citrus hybrid, a cross between mandarin orange and citron. It’s a favorite fruit in parts of India and South Africa, but here in the U.S., it’s used as a rootstock for Orange trees. A rootstock is a plant (tree) that is used to graft the desired tree onto it. The Rough Lemon is cold hardy, a large tree and does well in dry environments once it’s established.

What is The Difference Between Rough Lemon and Other Lemons

But what about its fruit? Yes, these lemons are on the ugly side, but in my opinion, they taste sweeter than other lemons yet still retain the sour taste. It makes excellent lemon juice.

Is there a real difference between lemon and Rough Lemon? Both citruses originated in Burma, in a region of North Eastern India (foothills of the Himalayas),  and northern China. At the end of the 15th or early 16th century, Rough lemon may have been transported to southeast Africa by the Portuguese and then taken to Europe. It reached the New World not long after that.

The acid content of these citrus fruits is different with Rough Lemon being more acidic than the ordinary lemon and easier to peel. Other lemon hybrids, such as Meyer Lemon is a hybrid between citron and sweet orange with the juice being less acidic.

Rough Lemon Uses

Rough lemons can be used just like other lemon types. Slices can be served as a garnish on meat or fish or with hot or iced tea, squeezed for its flavorful juice.

Lemon juice is widely known as a diuretic and astringent and when used in hot water is widely known as a daily laxative and preventive of the common cold. Concentrated lemon juice or lemon juice and honey, or lemon juice with salt or ginger, is one of the best cold remedies. It was the juice of the Mediterranean sweet lemon, not the lime, that was carried aboard British sailing ships of the 18th Century to prevent scurvy.

    Wow babe, this is A LOT of great, simple, valuable information you’ve given here.
    Thank you!

      Thanks! Looking forward to having Rough Lemons in our boxes this coming week.

    This is awesome. I just bought a house in LA with a lemon tree and these are my exact lemons. Thanks for this great information.

      Fantastic. Lemon trees are very productive and one single tree is more than enough for a family to use fresh and “Put Away” (Canning). We have citrus in our boxes as much as we can for our customers for this very reason. Have fun in your new house!

      One of my neighbors had a Rough Lemon growing in an orange tree. Now I know how that was possible. It must have been an offshoot coming up from the root. I agree the the R.L. had a very sweet, almost delicate flavor, yet much more “lemony” than a Meyer. I also enjoyed eating the peel. It was much less bitter than other citrus. Unfortunately, my neighbor removed that branch and a subsequent owner cut down the tree completely. I still see them, RARELY, around the San Fernando Valley. But, it has been at least thirty years since I’ve had one. (No exaggeration)
      M.B.

        Thank you for a great memory. I never thought about the peel. Thank you for sharing that.

        Keep on the lookout for our rough lemons coming up soon. I’d love to try to get you some.

    Makes good marmalade too. I just finished a batch. They’re a bit of a pain to peel, but the result is worth while.

    • Randall Farrar on January 10, 2020 at 4:49 pm

      We agree! Thank you for sharing. A very good underrated lemon. We look forward to proving them in our box again soon

    I have a tree in my home. I’m very confused about rough lemon and yuzu. How I can know the difference , please.

    • Randy Farrar on May 8, 2020 at 5:20 pm

      I’m not an expert, but the Yuzu has very little juice and very rare here in the US.

    I have a Meyers Lemon in the ground. Bore fruit for two years. We then had a very cold winter (Savannah GA). The grafted part appears to be dead but the stock is coming back. I am uncertain as to how to prune it. The limbs are fairly straight up with large thorns. Is this a rough lemon that was used for grafting??

    • Randy Farrar on July 3, 2020 at 12:57 pm

      Sorry to hear that you lost your Meyer. But the root stock coming up is either a Sweet Orange or rough lemon. Both have thorns and are used as root stock for Meyer Lemons. I would just train it to one trunk and let it start to branch at about 3 feet up. The thorns on the trunk can be pruned off.

      You now have a much hardier citrus tree than the Meyer and it will be edible for Juicing.
