A lime is an un-ripe lemon, kind-of

Here are the pics

The thing that confuses me the most is...It bares both green and yellow fruits. So...is it a lime, a lemon or a 'ripe' lime...?

Also...Does anyone know the cultivar...?

Could be a Meyer or a seedless key lime. Green means not ripe; yellow is ripe. How does it taste?

One of them might be from the tree's rootstock.

I don't think my cultivar is a Meyer. I looked at some Meyer lemon images on google and my yellow ones look nothing like the Meyer. The Meyer has seeds and it has a thick rind. My yellow ones have a thin rind and no seeds.

As for the taste...I have no idea as I can not tell the difference in taste between limes and lemons. My whole life...Lemons and Limes have always tasted the same to me as far as I am concerned.

In any case your tree looks to be seriously underfed. The best way to "taste" them, in my opinion is to mix with water and sugar. Based on your description my best guess would be seedless Mexican/key lime

That looks identical to the fruit of my persian lime and the leaves also. Listen to John and feed that tree. The reason you have different colors is because some are ripe and some are not. I have the same thing going on with my persian lime now even though it is potted. Also, the lack of seeds is indicative of a persian lime. All of my key lime cultivars have tons of seeds.

Laura,

If what you have looks exactly like that, it is NOT a Persian lime. The Bearss lime, developed in Los Angeles, California and most commonly sold as Persian lime or Tahiti lime is size and shape somewhere between Eureka and Lisbon lemon. Anyway it is all just opinion; but I am pretty sure that what the OP is showing is seedless key lime. If your key limes have lots of seeds, it is because you do not have the seedless cultivar.

Mine looks exactly like these, both leaf shape and fruit.

On the right is my “Persian” lime, middle - giant key lime, and left - regular key lime. My husband just cut one of the persian limes open but he juiced it before I could take a pic. It was totally seedless and looked exactly like the picture he posted above. He can compare pics and decide for himself...

That, Laura is a Bearss lime aka Persian/Tahiti. Nothing like a Key lime/now commonly called a Mexican lime.

I know John, but doesn’t that look exactly like the pic he posted above? I am sure what I have is a Bearss lime, but even the leaves of his tree look like the leaves of mine. The key lime has much smaller leaves and they do not cup upwards.

Whatever.

John, I am not trying to be antagonistic, I am merely expressing my opinion on the pictures the OP posted, which happens to differ from yours. I realize I do not have as much experience as you do with citrus, but I (and anyone here) should all be able to express our opinions here without being snapped at.

And what part of Internationally certified curmudgeon did you not understand? And FYI, if I were going to "snap at" you, "whatever" would not be my style.

Ok...then peace my friend ;-)

John Could you do a short video of your Guru grafting Meyer lemon trees. I would like to see how fast and easy it is for a professional citrus grafter to turn out a bulk amount of grafted Meyer lemon trees.

Sorry for the hijack! Steve

If you rip a leaf in half and smell it, you should be able to tell if it’s lemon or lime. Both my Persian and key lime smell exactly like lime fruity pebbles. My Meyer smells like lemon pledge. My mandarin leaves do not smell like oranges though.
