The variety is a hybrid of Japanese and American plum. The fruits have an oval-heart shape with a characteristic sharp tip; their average weight is 100–150 g, with individual specimens reaching 195 g. The skin is light yellow with a waxy bloom, and the flesh is yellow, juicy, and crunchy.
The variety enters fruiting in the 2–3rd year after planting and is partially self-fertile. The plant is characterized by high resistance to frost, withstanding temperatures from -28°C to -35°C, and good resistance to diseases, in particular to shot hole disease. The fruits ripen at the end of August or the beginning of September.
