Description Rouge de Florence, is also known variously as; Rossa di Firenze, Rossa Lunga Di Firenze, Rossa di Toscana, Long Red Florence, Florence Simiane, Italian Torpedo or Italian Red Torpedo. An outstanding long, red onion that I find a joy to both grow and to eat. I love this onion, the shape the colour and the outstanding flavour. In my garden it is one of the easiest and most reliable of croppers and can be grown right through the year. It stores quite well and can be used raw or cooked so this variety definitely makes it to my list of desert island veg.
The torpedo shaped bulbs have a deep purple red colour and robust flavour. According to the seedsman Thomas Etty this onion may be synonymous with the Ox-horn Onion or spindle shaped onion (ognon Corne de Boeuf) listed by Vilmorin in The Vegetable Garden, 1885 however I would disagree with M.Vilmorin who thinks that … ‘These [pear shaped] varieties, however, are more curious than useful’. In my opinion this is a really cracking onion for the home or cook’s garden.
Origin & History This is an old variety from Tuscan Italy which I think dates back to the 1800′s.
Flavour The flavour can be mild and delicious raw but it can also become quite pungent depending on the year and how the weather effects growth. I find some years these onions are stronger than others.
Cultivation Sow outdoors in early spring for a summer crop or late summer for a spring crop the following year. Sow undercover from winter and transplant in early spring spacing seedlings 5cm-8cm apart in rows 30cm apart. In my garden I have had the best results sowing in trays in November, pricking out into double trays in December-January and planting out late February -March to harvest a bumper crop after midsummer.
Plants are strong and reliable growers bulbing up nicely after midsummer. They withstand light frost, heavy frost seems to make them divide, drought and heat.
Harvest Grow in succession for use fresh – 2 sowings July-Nov and March-May will provide a continuous supply. For early spring onions leave some onions in the ground over winter and harvest the new green onions that are produced as spring arrives. Harvest when tops have died down and dry as for bulb onions, see my post on Harvesting & Storing onions. Rouge de Florence will store for about 6 months.
Use I use these onions for everything, you can even pickle the small ones.
Resistance a really easy going onion that will grow in poor soil and in tough conditions. An unstoppable onion.
USP When left in the ground overinter I’ve found that these onions multiply to form clumps of 4 or 5 green onions in the spring. These new green onions can be used as spring onions and are delicious.
