Apriums resemble apricots on the outside. The flesh is usually dense. Apriums are noted for their sweet taste, due to their high content of fructose and other complex sugars. Apriums are usually only available early in the fruit season, like apricots and unlike pluots, which include some very late-ripening varieties.

Aprium trees grow quickly and are smaller compared to other common home-grown apricots. The fruit is gold, with red coloration. Semi-mature fruit is hard and does not ripen if picked before completely mature.
