The name was historically used as a synonym for the "Cœur de bœuf moyen de la Halle" variety (also known as "Demi cœur de bœuf"). According to European Union documentation, this name in official white cabbage variety registries was often associated with the "Steenkop" variety.
The variety belongs to early maturity groups. The head has a conical shape, rounded at the apex and widening towards the base. Leaves are smooth and characterized by good quality. Traditionally, the variety was valued by gardeners for the combination of earliness and head volume, which ensured high productivity.
