The tree is medium-sized, reaching a height of 2.5–3 m with a crown width of 60–80 cm. The variety was obtained by crossing the varieties Ersinger and Cacak's Best. It is characterized by high and early yields without signs of biennial bearing.
Fruits are large, weighing 50–55 g, elongated in shape with blue skin. The flesh is green-yellow, firm and juicy, and the stone separates well. The taste is characterized as very good, with a pronounced acidity.
The variety possesses high resistance to Plum pox virus, Monilinia, rust, and fruit rot. It is distinguished by excellent frost hardiness, including the resistance of flower buds to spring frosts.
