I received my Nam Doc Mai mango in late July 2018, it didn't seem to grow very much but a few weeks ago it put forth 3 bracts of blossoms! The plant is only about 1.5 feet tall so it seems unlikely that mangos will develop, but still, after only a year it is blooming. Some of the leaves have brown on the tips, but this is likely due to (my) user error. I recommend this tree, even for growing indoors in a cold climate.
