This tree is vigorous, semi-erect, and has medium-wide crotch angles. It is resistant to bacterial spot, perennial canker and brown rot, and the fruit does not tend to skincracking. AC™ Harojoy ripens early to midseason, a few days after Harcot. The fruit is largish, glossy orange with an attractive red blush, very firm, and freestone. It is finely textured with a well-balanced flavor, and it is suited for home orchard or commercial production. AC™ Harojoy ranked very highly during taste trials. This tree is self-fertile but better fruit set will be obtained in the presence of a pollenizer. As with all apricots, thinning is recommended for optimal fruit size.

As Bob Purvis explains in Pomona, Fall 2006: "The earliest apricots brought to North America were mostly from Spain and similar Mediterranean climates, and they did not include the genes for a broader range of climatic adaptability. Modern breeders have sought out germplasm in many places, including central Asia where the apricot is thought to have originated." One such breeding program is based in Harrow, Ontario, and it has produced the "Harrow Series" of cold-hardy apricots that are suitable for New York and New England. AC™ Harojoy was released by this program in 2000. It is an offspring of Harlayne and Harcot.
