The variety forms a vigorous tree with a spreading crown, reaching a height of 3.5 meters. The variety has good winter hardiness and high resistance to diseases such as shot-hole fungus and plum rust.
Fruits have an oval shape and medium size (30–45 g). The yellow juicy flesh of medium density is distinguished by a sweet taste with a honey undertone; the stone separates well. The variety is self-infertile and matures in early August.
The plant is characterized by regular and abundant yields. To maintain productivity, it is recommended to perform spring pruning.
