Taro is a tuber, not a fruit; it grows into a plant like elephant ears.
You can get it at HEB or Fiesta. You'll find oranges much more exciting,
imo. When cooked into poi, it's pretty bland and starchy. Mmm...

Black sapote (sapote negro) is like a persimmon. You can find them at
Mexican markets, but you'll probably face the same problem you're having
at HEB. Lychees are usually available fresh (and always available canned
in syrup) at Asian markets; I've only seen them once at HEB. You can
sometimes get them at Mexican markets. Same with durians. I often see
both at Asian supermarkets if I pay attention.

Try printing out pictures and say, "Yo deseo éstos, por favor" ("I want
these, please"). Or find another employee who speaks English.
