Mr. Yee's family has had this orchard since 1945. He's getting up there in age. Development is crowding his small orchard. Something tells me once he goes, so goes his orchard.
That said, if you find yourself on Maui, do your taste buds a favor and seek out his fruit stand, which appears to be manned solely by an elderly woman. It is located on the west side of So. Kihei near Lipoa in a wooden shack in the middle of a dirt parking lot. There is one modest, weathered handpainted sign. We stopped by on a Thursday morning, but it was empty. A passerby told us it usually opens at 11:30am. We returned about then and bought some of the best tasting fruit I've ever had.
Mr. Yee has developed a mango he calls Golden Glow, and the only place you can buy it is his little shack on So. Kihei. It is a flavor-explosion (do a google search on "golden glow mango" to see other descriptions). He also sells Haden mangoes, tomatoes, onions, apple bananas, papaya, passionfruit, chicos and sugarcane...along with many other fruits I couldn't recognize. Bring cash, or stop at the nearby Long's Drugs or Star Market and withdraw some, because they don't take plastic or checks.
We tried to stock up on mangoes on our way to the airport for our departing flight--it was Monday afternoon--but nobody was at the stand. We ended up hitting the Kihei farmer's market, but were advised of the rule prohibiting taking mangoes home....which has got to be the dumbest rule I've ever heard of.
The lesson here is:
a) find this place,
b) early in your trip,
c) take cash, and
c) buy all the mangoes (especially Golden Glows) you can get your hands on.
