The nursery where I have bought some plants in the past also sells a red lemon. I haven't seen this anywhere else before. Is this an unusual kind of citrus?

It looks like red rough lemon (C. jahbhiri) rather than a true lemon (C. limon). Here in Florida, the yellow form is certainly more common, but one does see the red form occasionally. We had a tree of it on our college campus for many years.

What is the taste quality of a Red Rough Lemon? - Millet (1,035-)

seems like we has another thread about a red citrus on this forum before like two years ago or so.

Red rough lemon tastes exactly like normal RL to me. Pleasantly lemony, but not exactly the same as C. limon. Still more lemony than a 'Meyer'.

Thanks for the answer the Red Rough Lemon. As for Meyer lemons, which are an enormously popular tree among hobby container citrus growers, I never could figure out why they are so popular. Meyer lemons do not have the sweet taste of a good orange, nor does it have the clean crisp taste of a lemon. Meyer lemons are stuck half way in the middle. All that said, I am growing two Meyer lemon trees, of which we (my wife and I) don't use the fruit all that much. Guess that is why they make Fords and Chevrolets. - Millet (1,034-)

I agree with Millet - Meyer lemons don't function that well as a lemon, and are not much use as an orange. I have two in the ground, one on purpose, the other was bought as something else. I have used the juice a couple of times when making marmalade, but usually I give all of them away.

Meyer lemon juice can be used to make great tasting lemonaide and lemon bars. The fruit has extremely high juice content and one cup of juice can be extracted from just two meyer lemons.
