Variety description

10 August 2026

The hybrid forms dense stem bulbs weighing 0.6–0.75 kg. The variety is positioned as versatile and stable, recommended for sowing in June for harvest in November, although cultivation options from spring to early autumn are also possible.

An important characteristic is high resistance to the formation of flower stalks. When selecting seeds, it is necessary to consider the Latin name of the species Foeniculum vulgare, as the name Leonardo F1 is also used for varieties of other vegetable crops.
