This is from the West Palm Beach, FL area and was introduced in 1922.
Its parentage is unreported but it is probably a Mexican-Guatemalan hybrid.
It was later trialed in other parts of Florida and found to be fairly cold hardy (down to the low 20sF).
Though it was reported to be a very vigorous variety, this has not been our experience with it and the tree has grown rather slowly.
It produces small-to-medium sized, green pyriform shaped fruit with pale colored flesh and somewhat mild flavor.
As the name suggests, Winter Mexican is a late-season avocado here maturing its fruit from December through January.
It produces B-type flowers.
