The variety is early-maturing, with a period from planting to technical maturity of about 65 days. The plant is characterized by vigorous growth, a short core, and the formation of a small number of outer leaves.
The heads have a pointed shape with a softly rounded top, characterized by a dense structure and light green leaves of a delicate texture. The variety is characterized by uniform maturation, but requires harvesting in a tight timeframe to prevent cracking.
Suitable for cultivation in open field from spring to autumn, as well as under plastic covers. It is a "samenfest" type variety (not an F1 hybrid), which allows for independent seed saving.
