The tree has moderate to weak growth vigor, forming a spherical crown with spreading branches and drooping shoots. The variety is mid-early or mid-late, with the harvest taking place in late August — early September. Fruit ripening is often uneven, which requires multiple pickings.
Large fruits weighing 40–50 g have pink-red or pink-purple skin with a waxy bloom. The flesh separates easily from the pit. The variety is self-fertile and does not require pollinators, although fruit thinning is recommended to improve fruit quality.
The plant has low winter hardiness. Resistance to plum pox virus is noted, while the variety is susceptible to fruit rot. Shoots are prone to brittleness under the weight of the crop, making it necessary to perform formative pruning.
