The original tree was grown from a seed on the property of Walter B. Eldon in Miami, Florida in 1939. Reportedly the seed had been a 'Haden' seed, and a 1995 analysis supported this; however a 2005 pedigree study did not support this, estimating that 'Eldon' was likely a seedling of 'Cowasji Patel' instead. The original tree first fruited in 1942. Propagation was begun around 1948 by Lawrence Zill and J.W. Chafer.
While 'Eldon' did not become a popular nursery stock tree in Florida over the following decades, it did eventually gain commercial acceptance in Africa.
'Eldon' trees are planted in the collections of the USDA's germplasm repository in Miami, and the University of Florida's Tropical Research and Education Center in Homestead, Florida. 'Eldon' may have been a parent of the 'Southern Blush' mango.
The fruit is of oval shape and averages about a pound in weight; moreover, the fruit may have variegated color upon maturity, and can be a mix of green, yellow, orange and red blush. The flesh is yellow and has a sweet flavor with a pleasant aroma. The fruit contains a monoembryonic seed.
The trees are moderately vigorous with a large canopy that contains light green leaves.
