Years back I got "Glenn" scion wood from a Florida member at Garden Web. I grafted it to Indian seedling rootstock and it sat and sat for over a year, finally sending out a tiny bud from the scion (all other grafted material perished). Today that tardy experiment is an espalier in my little greenhouse and this past September it produced a lot of excellent mangoes. Neighbors raved about them. Alas, we only had two since we were set to travel as they started to ripen
But I don't think they are Glenns. If Google is to be trusted, Glenns look sort of like the kind of mango you would find at a supermarket anywhere in the country (excluding the manila type). These mangoes--at least grown under my conditions--have rough grayish skins which blush just a little when ripe, funny shoulder bumps that tend not to ripen fully, and come to a near-point at the end. The flesh is completely fiber-free, luscious and redolent of coconut. The seed is amazingly thin and narrow for such a large fruit. In short, they are wonderful. The tree blooms like it's the last chance to reproduce the species.
Any guesses?
