[3] Palmer trees are planted in the collections of the USDA's germplasm repository in Miami,[4] the University of Florida's Tropical Research and Education Center in Homestead, Florida,[5] and the Miami–Dade Fruit and Spice Park,[6] also in Homestead.

The fruit is large, with especially big specimens reaching several pounds in weight.

The flesh is orange-yellow and has a mild and aromatic flavor, with minimal fiber, and contains a monoembryonic seed.
