Have you ever tried a Mexican Sweet Lime? The shape is different from other Limes or Lemons. This one looks more yellow than green when ripe. It is not very sour and is very refreshing as an eat out of hand fruit or in a refreshing beverage (with or without a sweet or alcoholic addition for flavoring). It needs some frost protection but is very vigorous and easy to grow. It gets big faster than some dwarf citrus and the fruit stay on the tree long for long harvest timing. Kids love them and so will you. Ask to try one.
