Variety description

10 August 2026

The plant is vigorous, with a well-developed leaf canopy. Leaves are dark green, glossy, and covered with a strong waxy bloom. Bulbs are uniform, round or slightly round-flat in shape. The average bulb weight is 90–150 g; dry scales are golden-brown, and succulent scales are white. The neck is medium-thick or thin.

The maturation period of the hybrid varies from 75 to 105 days. The plant possesses high resistance to bolting, diseases, and pests, and is also capable of tolerating drought due to a developed root system. A dense double husk protects the bulbs from mechanical damage and ensures good keeping quality during storage.
