The variety is an open-pollinated type and is characterized by a compact plant size with a small number of outer leaves. The growing season typically ranges from 70 to 80 days, in some cases varying from 60 to 100 days.
The heads are distinguished by their density and ability to remain in the field for a long time after maturation without cracking. The variety shows resistance to bolting.
The produce has a sweetish taste and a crispy texture, which makes it suitable for fresh consumption, salad preparation, and sauerkraut production.
