Also known as President Roosevelt. The original tree of the President was grown by Griffing Brothers of Macclenny, Fla., about 1889 from a nut obtained by them from Bagdad, Fla. The tree was sold by them in 1891 with other seedlings to a customer who planted it in Jacksonville, Fla. Its propagation was begun about 1902 (Sparks, 1992).
*Note: This is an older cultivar planted in the Old Variety Test at the Tifton Campus. Trees were planted decades ago when care was very different than it is now, and trees received much less care, so production data will reflect this fact. Trees began receiving insecticides in 1962, fungicides in 1970, nitrogen in 1962, and drip irrigation in 1975. The data for this cultivar was collected by several individuals, but the bulk of the data and the comments are from my predecessor Dr. Ray Worley. This information was originally published here: Worley and Mullinix, 1997.
It has a small nut with low percent kernel. One of the trees was affected by a canker and yield was low on it. Mediocre at best, not recommended.
