I have an unknown type of lime tree (not a dwarf) planted in an 18-inch clay pot. Received as a housewarming gift in February 2013 from a relative (who lives further south and doesn't garden). I just don't have the time or expertise to invest in this tree. It's in pretty good shape; has never born fruit. You must be able to pick it up from my home in Atlanta (I live close to I-75 in Buckhead) and take it away without my assistance (bad back). Free tree, pot and soil! Total height from bottom of pot to top of tree: 7 feet.
(Sorry about the diagonal photo...couldn't fit the whole tree in without turning the camera sideways.)
