Meyer Lemon-a secret of chefs for years, this citrus fruit is believed to be a cross between a true lemon and a mandarin. As a result, Meyer lemons have sweeter juice than most others as well as aromatic flavor. Their small, compact design also makes them ideal for ornamental purposes.

Palestine Sweet Lime-while this lime is a common backyard tree in the Middle East, it is almost never seen in a traditional market. They are juicy, slightly bitter, but mild when compared to more familiar varieties of lime. This is due to the lower levels of acid in the fruit.
