Variety description

10 August 2026

The variety is ultra-early; with autumn sowing in a warm climate, harvesting is possible as early as mid-to-late March. The plant has an upright growth habit, short leaves, and a developed root system, which ensures vigorous development.

The bulbs have a high-round shape and an average weight of about 250 g. The dry scales are light yellow in color; the internal scales are distinguished by juiciness and a sweet taste. The variety is valued for the good uniformity of the bulbs and high yield.

Successful cultivation requires strict adherence to sowing dates, as early sowing in the fall can trigger bolting and bulb splitting. The variety is adapted to climatic zones with mild winters, such as the Mediterranean.
