The period from transplanting to technical maturity is 50–55 days. The heads have a light green color and grow on low stalks. The variety is not intended for long-term storage and requires timely harvesting, as it is prone to cracking if left in the field too long.
The plants do not require staking. For cultivation, a planting scheme of 50 × 40 cm is recommended on fertile, humus-rich, and water-retentive soils. The variety is sensitive to moisture fluctuations, requiring regular watering to ensure normal head growth.
