Here's a few for the fruit hall of shame 

1) Noni (smells like an outhouse)
2) Quince (tastes like soft wood)
3) Kiwano / African Horned melon (why are these even sold?)
4) Pond Apple (Annona glabra) Racoons love them 
 
Also in this group, are those Mangos grown in places like Peru and Mexico that are picked a month before they
are mature, then refrigerated, hot dipped according to USDA requirements and sold here in Florida and elsewhere
in the US for 50cts to $1. The vast majority of these are HORRIBLE     

That would be the infamous Tommy Atkins mango, wouldn't it?  (I'm thinkin' I wanna grow noni for its medicinal value.  Who knows when it might come in handy!)

WAY BACK in the 70's when I lived in Hollywood, CA, in my twenties, there were some organic citrus growers in north San Diego County who grew THE BEST Minneola tangelos.  Towards the end of the season, they were the sweetest, most flavorful citrus imaginable.  We'd drive down from L.A. and bring back several boxes for all our friends.  Good times! 

1. Mango
2. Peach
3. Cherimoya
4. Japanese Plum
5. Fig

Honorable mention: Lychee, Avocado, Sweet Cherry, Apricot, Tangerine/Mandarin, Pineapple, Apple (an heirloom variety), Valencia Orange (end-of-season), Japanese Persimmon, Comice Pear, Muskmelon, Honeydew.

Don't know how, but thanks for the offer.

I'd like to know when SouthFlorida has had a freeze in April, or even March or February, for that matter.  Sounds VERY far-fetched (bordering on impossible) to me!

Where can we purchase a "Big Red" sugar apple tree?

Did you leave out the "where" and the "when?"
