The original tree was grown from a seed planted by Michael Fascell of Miami, Florida in 1929, and was likely a cross between 'Haden' and 'Brooks'. Fascell's intention was to create a variety to fill the gap between the harvesting seasons of 'Haden' and 'Brooks'. The tree first fruited in 1936. Fascell, a nurseryman and prominent member of the Florida Mango Forum, patented the fruit in 1941 (plant patent number 451), making the 'Fascell' one of the first patented mango varieties in Florida. Beginning in 1942 the tree was sold as nursery stock on a small scale. Though it never became a popular dooryard tree, 'Fascell' is still grown on a small commercial scale in Florida.
The fruit is of oval shape and has no beak, has a laterally compressed appearance, and often appears heart-shaped. It turns yellow at maturity with a distinctive bright carmine colored blush. The flesh is sweet and fiberless, containing a monoembryonic seed. It typically matures from June to July in Florida.
'Fascell' trees are vigorous growers with spreading canopies.
