10 August 2026
The tree is distinguished by its hardiness and ability to grow in various types of soil, from clay to sandy. The variety demonstrates stable yields without showing pronounced biennial bearing.
The fruits are approximately 2.5 by 3 cm in size with an average weight of 10.4 grams. The skin is bright yellow, the flesh is characterized by a high sugar content, and the pit separates easily. Fruit ripening occurs at the end of summer.
The variety was historically used in family gardens, and the trees often served as living supports for grapevines. Due to their taste qualities and the ease of pit separation, the fruits are used primarily for making jams.
