Zebrune is a heritage variety grown widely in France where shallots are revered in cooking. Torpedo shaped, they are often referred to as 'banana' shallots. Milder and sweeter flavoured than onions. Just as easy to grow. When dried well shallots can be stored for even longer than onions.
Being daylength sensitive, shallots grown from seed should be planted as early as possible. This allows the most opportunity for growth before the bulbs start forming. I aim to start them in a heated propagator from around February.
