10 August 2026
The tree of the variety grows with moderate intensity, forming a small, sparse, spherical crown. The fruits are medium to large in size, teardrop-shaped with a characteristic narrowing at the stem. The dark blue skin is covered with a glaucous bloom and small light dots; the flesh is greenish-yellow and firm. The small, rounded stone is difficult to separate from the flesh.
The variety belongs to the early-ripening group, maturing in late July to early August. It bears fruit regularly and abundantly, entering the fruiting stage early. The tree is winter-hardy and resistant to fruit worm infestation. The variety is self-sterile and requires the presence of pollinators such as Dolanka, Vlaška, or Wangenheimova. The fruits prefer warm locations and fertile soils; they hold well on the branches upon ripening but have low transportability.
