Mississippi origin; thrives in warm, humid climates.
The Cauley apple originated as a chance seedling in the yard of John Cauley in Grenada, Mississippi, sometime in the first half of the 1800s. It was widely cultivated throughout the American South for decades but had nearly vanished by the turn of the century.
 
According to Creighton Lee Calhoun, author of Old Southern Apples, a surviving tree was discovered in 1919 on the property of John Cauley. From this tree, J.W. Willis obtained cuttings and grafted them onto three rootstocks at the Delta Branch Agricultural Experiment Station in Stoneville, Mississippi. The Mississippi River flood of 1927 destroyed two of these, but one young tree survived. This tree was reported to produce up to a ton of apples each year, and all subsequent trees of this variety were propagated from its cuttings.

Calhoun also noted that Crawford Nurseries of Concord, Georgia, marketed a similar apple called Cally in the early 1920s, which they described as having originated in Mississippi "over 50 years ago." It is highly likely that Cally and Cauley are the same apple variety.
