Yellow Flat Onion
A traditional garden onion widespread across Northern Italy, the yellow flat onion is famous for its excellent kitchen yield and long winter storage life.
The Yellow Flat Onion Plant
Allium cepa yellow belongs to the Amaryllidaceae family. The vertically compressed bulb develops tough amber skins, which act as natural protection against drying out during storage.
How to Sow Yellow Flat Onion
It is sown in late summer, between August and September, for overwintering seedlings, or in early spring for direct field sowing in colder areas.
How to Grow Yellow Flat Onion
A sturdy, adaptable plant, it tolerates both clay and sandier soils well, provided they are drained; light mulching helps control weeds without stressing the roots.
Tips for Yellow Flat Onion
The ideal harvest time is when about 50% of the foliage has naturally bent over; early harvesting would compromise the bulb's storage capacity.
Diseases and Pests of Yellow Flat Onion
It can be subject to downy mildew and neck rot in conditions of excessive soil moisture; common pests include onion fly and thrips.
Uses and Curiosities of Yellow Flat Onion
It is the everyday kitchen onion par excellence: perfect as a base for sautéing, risottos, sauces and winter preserves thanks to its strong flavour that mellows with cooking.
Properties of Yellow Flat Onion
Yellow onions are rich in quercetin, an antioxidant flavonoid, and also have diuretic properties, plus a good vitamin C content.
