The variety is the result of crossing the Pacific and Albion varieties. The tree is medium-sized, reaching a height of 3–4 meters, and possesses a dense, compact crown of rounded or broad shape. The variety is characterized by high winter hardiness, the ability to withstand frosts down to -28...-34°C, and high resistance to stone fruit diseases. Late flowering times allow the tree to avoid recurring spring frosts.
The fruits are large, weighing 50–70 grams, of an elongated and often asymmetrical shape. The skin is dark purple with a waxy bloom; the flesh is firm, juicy, yellow in color, with a sweet taste and honey aroma. The stone separates well. The variety is partially self-fertile; to increase yields, pollinators such as the President and Stanley varieties are required.
The fruits are for universal use, suitable for fresh consumption, dessert preparation, and canning. The firm skin and flesh structure ensure good transportability of the produce.
