Onion -
Rossa Longa di Firenze onion is a traditional torpedo shaped red onion from Italy, producing good size bulbs with deep purple-red colour.. To ensure a good crop, plants must be growing strongly by late spring, as the lengthening days trigger the formation of bulbs – the more leaves plants have at this time, the better the bulb will be. Early sowings (December to March) can be made indoors.y.
