Many gardeners swear that this is the most attractive heirloom Florence fennel around, as well as one of the most succulent. The bulbs are large and can get up to 1kg, but don’t grow it for the bulbs alone! Use the leaves in salads, the stems in stir fries, and the seeds as a seasoning.
This variety prefers to be sown later in the spring. (Sow it too early and the bulbs will be smaller).
