picked up a few dwarf hawaiians from TT last week. They were small and tasty. The fruit has a small amount of fiber, but not objectionable at all. Has a multitude of tastes. Startss out like regular sweet mango flavor, slight citrus detected, then a slight resinous flavor that was balanced by the sweet so that it wasn't a turn-off at all. Then it finished with notes of coconut water/vanilla (subtle, but there) that is refreshing. I asked the wife, would you want a tree of this variety, She didn't even blink--just answered Yes! immediately. If it were ripe in July, it wouldn't be remarkable, but those were the last of the season (last week), so it is great to have mangoes this time of year. I have only tried one early rosigold, and found it good, but not great--kinda rubbery and not complex.
Pros: flavor complexity, compactish tree, little fiber, available when little else is.
Cons: slight bitterness near skin, small fruit
I believe Chris will be grafting DH trees for those who are interested.
