The growing period of the hybrid is 85–90 days, reaching 115 days under certain conditions. It is an intermediate-day hybrid, exhibiting high growth energy and developed foliage. The plant is resistant to bolting.

The bulbs are round in shape, with snow-white outer scales and firm, juicy flesh. Bulb weight ranges from 120 to 250 g, and can reach 800 g with intensive care. The taste is characterized as mild and semi-sharp.

The hybrid has high resistance to pink root rot, as well as intermediate resistance to Fusarium basal rot and downy mildew. It is intended for the fresh market and is suitable for short-term storage of up to 4–6 months. Transplants or direct sowing in the ground are both possible.
