The variety belongs to mid-early hybrids with a period from transplanting to harvest of 44 to 64 days. Medium-sized plants form a central head with a diameter of 10–20 cm and a weight of about 450 g. The variety is capable of forming side shoots after the main head is cut, which extends the harvest period up to three months.

This hybrid is characterized by high adaptability to various growing conditions and heat tolerance, which allows it to be used in both spring and autumn production cycles. In the scientific community, the variety is often used as a reference sample or a model object for breeding research.
