Glenn was a seedling selected in Miami, FL by Roscoe Glenn in 1944. It was reported to be a Haden seedling but Roscoe Glenn affirmed that it was actually a seedling of a ‘Saigon’ mango. Haden was probably the pollinating parent though.
The trees are medium size growers with dense canopies, and are regular producers with good anthracnose resistance, and fruiting well. They have a mild peachy flavor that is delightful during dry weather, though can be washed out under humid conditions. The fruit are small-to-medium sized and develop nice red or orange blush at maturity. They make excellent trees for home growers, and ripen early season.
