The tree that these lemons come from originates in Turkey (via Citrus Variety). From what we can understand, the University of California took the tree and grafted it with a Ponderosa lemon tree, successfully altering the tree to produce fruit. The resultant lemon has an early harvest of medium-sized fruit with an elongated and cylindrical appearance, notes Fresh Fruit. Lamas lemons have a uniform peel that's shiny and easy to zest.
