Description
The Paris Silverskin white onion will produce small white bulbs with a mild flavour. This fast-growing variety is sown in spring and harvested during summer.
The onion is a plant cultivated as a vegetable and a condiment. It is the fleshy bulb that is consumed, sometimes the stems in the case of chives.
There are 3 groups of onions, distinguished by the colour of the bulb:
white onions, early varieties, consumed in vegetable gardens for example or pickled in vinegar,
yellow onions, for storage, often consumed cooked (soups, pissaladières, compotes as accompaniments to cheese or charcuterie),
red onions, usually consumed raw in salads.
Onions are rich in vitamins A, B, C and minerals, often more digestible and sweeter when cooked. To avoid crying while cutting an onion, you can peel it under running water, in a basin of water, or wear swimming goggles!
Onions originate from Central Asia where they have been consumed for over 6000 years. They were present in the tombs of the pharaohs as a food supply. Their therapeutic and gustatory virtues were already recognised. The Romans later introduced onions throughout Western Europe. It is also worth noting that Christopher Columbus introduced onions to the Americas during his second voyage.
Harvesting: White onions are harvested in spring when the foliage is still green. Coloured onions (yellow and red) are harvested in summer when the stems are completely dried and bent to the ground. Gently pull them out and let them dry for two to three days on the ground in the sun. Remove excess dried soil by lightly rubbing them.
Storage: Onions can be stored for several months under good conditions. If the condition of the stems allows, you can make a braid and hang the resulting bunches. Otherwise, cut the leaves and store the onions in a dark, cool, dry, and well-ventilated place. Check beforehand that they have not been bruised to avoid rotting, which could contaminate the entire harvest.
The gardener's tip: alternate rows of onions and carrots to keep the carrot fly and onion fly away. Additionally, onions thrive in the company of beets, strawberries, and lettuces.

Planting and care
Soil preparation: Onions thrive and grow in all types of soil, preferably light and well-drained. The soil should not have received any manure for at least a year. Onions dislike excess nitrogen, so avoid planting them after green manure or legumes from the Fabaceae family (beans, peas, fava beans). Rotate the crops every 5 years before growing onions again.
Spring sowing: Coloured onions (yellow and red) and some early varieties of white onions are sown from February to April, directly in the ground (or in autumn if the climate is mild). Mark the rows by stretching a string and spacing the rows 20 cm apart. Dig a furrow 2 cm deep and sow thinly. Close the furrow by lightly tamping with a rake. Moisten the soil immediately afterwards. Germination takes about 18 days. When the plants reach 5 cm (about 2 months after sowing), thin them out, leaving one plant every 10 cm. Harvesting can then be done throughout the summer.
Autumn sowing: White onions are sown at the end of summer (August-September) in trays or pots. They will be transplanted into the ground either a month later in mild climates or at the end of winter around February. Allow 20 cm between rows and 10 cm within the row. White onions are then harvested in spring.
Regular tasks: Regularly hoe the soil, especially at the beginning. Avoid mulching to prevent rotting. Onions dislike moisture, so watering should be kept to a minimum, mainly during sowing and transplanting.
It is also possible to produce bulblets yourself: sow in March and keep one plant every 2 cm, harvest bulblets with a diameter of less than 2 cm in July, store them dry during winter, and plant them out the following spring.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
