The variety is classified as mid-early, with harvest taking place in the second half of September or early October. The tree enters the bearing stage in the 2–3rd year after planting. Growth habit varies from very vigorous with a wide crown to weak, which allows it to be grown in small orchards.
Nuts are medium or small in size, round or slightly elongated in shape. The shell is very thin. The kernel is yellow, sweet, fills the shell completely, and is covered with a light brown skin. To obtain optimal yields, it is recommended to plant pollinator varieties nearby, such as «Lake» and «Jupiter».
Ornamental value is provided by large, serrated leaves with a lemon-green hue. The variety is characterized by average resistance to frost, diseases, and pests, although a number of descriptions list it as exceptionally resistant to diseases.
