So after a few seasons to make sure it wasn't just a fluke im excited to report that I have stumbled upon a veriety that produces delicious mangos in winter. It has done so for several seasons in a row, not a motherload of them but enough to warrant a real evaluation and a determination of whether it is a new or forgotten veriety.
The tree is likely between 30 and 40 years old, and 30 pluss feet tall. planted in the yard of a home built in the early 60's in merritt island, the current owner who has lived at the property for 8 years and was not passed on any info on the tree.
The tree produces a bountiful summer crop without being sprayed, some anthrcnose susceptibility but the skin seems to keep it out of the flesh. The summer crop is certainly more flavorful but the winter crop is still fantastic. I would put it in the classic sweet profile with fiber comparable to certain commercial veriety but not objectionable.
I will continue to update with an in depth evaluation as the season unfolds. Unfortunately there are no more fruit on the tree this winter, but I will post pictures and keep track of its progress.
