Potato onions
(0)
$18.00
Unit price / perKnown as the potato onion, this traditional group of onions forms clumps of bulbs, somewhat like a nest of small potatoes at the base of the foliage. Long cultivated in family vegetable gardens in cooler climates, it has maintained a reputation as a reliable plant, easy to maintain and replant year after year.
In the garden, the potato onion offers hollow, bluish-green foliage reminiscent of the common onion. The bulbs divide into several cloves that are replanted, in an almost circular process where the harvest nourishes the next cycle. It naturally finds its place in a vibrant and diverse garden, along the edge of a bed or in a quiet corner of the vegetable patch, where it accompanies other vegetables in a patient and deeply rooted relationship with nature.

Known as the potato onion, this traditional group of onions forms clumps of bulbs, somewhat like a nest of small potatoes at the base of the foliage. Long cultivated in family vegetable gardens in cooler climates, it has maintained a reputation as a reliable plant, easy to maintain and replant year after year.
In the garden, the potato onion offers hollow, bluish-green foliage reminiscent of the common onion. The bulbs divide into several cloves that are replanted, in an almost circular process where the harvest nourishes the next cycle. It naturally finds its place in a vibrant and diverse garden, along the edge of a bed or in a quiet corner of the vegetable patch, where it accompanies other vegetables in a patient and deeply rooted relationship with nature.
- Growing climate: Cool season
- Sowing difficulty level: Medium (cultivation mainly from bulbils rather than seeds)
- Care required: Occasional
- Growth: Summer growth
Note: Tolerates cool climates and cold winters well when well mulched; hardy and long-lasting plant in the garden.
Potato onions are cooked like regular onions: raw in thin slices, sautéed, simmered, or roasted. Their often smaller size and division into cloves make them practical for everyday cooking: you take one or two bulbs as needed.
They are prized for stews, soups, and casseroles, as well as for baking, whole or quartered. The relatively long shelf life of well-dried bulbs makes them a valuable resource for extending winter food supplies.
Traditionally, this type of multiplying onion is often kept from year to year in families, passed down as a local "stock", which fosters a strong link between the garden, the table and the memory of ancestral gestures.
