The tree has vigorous growth and can reach 5 meters in height when formed as a half-standard. The variety is self-fertile and precocious, entering into fruiting 2–3 years after planting, and is characterized by stable yields. The plant possesses winter hardiness and resistance to the plum pox virus.
Fruits have a round or round-oval shape, golden-yellow skin, often with red dots on the sunny side. The golden-yellow flesh is juicy, firm, and easily separates from the stone. Fruit weight varies, with basic data ranging from 16–20 g. The harvest ripens in the period from mid-August to September.
