‘Rossa di Milano’ Onion (Allium cepa). The ‘Rossa di Milano’ onion is as appealing for the elegance of its deep red bulbs as it is for the sweet tenderness of its flesh, highly sought after in the kitchen and in home gardens. Throughout the season, its upright foliage captures light and indicates the formation of firm bulbs with a slender neck, perfect for good preservation. Grown in full sun in loose, well-drained soil, it fully expresses its vigor and appreciable tolerance to cooler climates. In the kitchen, its mild flavor allows it to be used both raw and cooked, in salads, onion jams, or stewed dishes.
Recommended sowing period: indoors from February to March, outdoors in early spring. The depth to respect is 1 cm (3/8 in). Germination usually takes 8 to 12 days. For germination, maintain the potting soil at 15 to 21 °C (59 to 70 °F). Keep onion, leek, or shallot seedlings well identified, as their young foliage looks similar. Sufficient light and regular moisture accompany the growth of seedlings. Transplant delicately when the type of cultivation requires it, without crushing the base of the leaves.
This ancient variety brings a heritage touch to the garden, while offering a generous and regular harvest that rewards both beginner gardeners and traditional seed enthusiasts. Rows of onions and leeks are suitable for areas of the vegetable garden where you can work without walking between plants. Their vertical silhouette can border a more sprawling crop, provided that the foliage receives enough light. Identify varieties for bunching and those for bulbs to choose the right harvest stage. Keep the row accessible for weeding until the plants are well established.

Growing method
Recommended sowing period: indoors in February-March, outdoors early spring. Sow to a depth of 1 cm (3/8 in). Emergence generally takes 8 to 12 days. For germination, maintain the soil at 15 to 21 °C (59 to 70 °F). Keep onion, leek, or shallot seedlings well-identified, as their young foliage looks similar. Sufficient light and regular moisture accompany seedling growth. Transplant carefully when the crop type requires it, without crushing the base of the leaves. In the garden, prepare a surface that is easy to weed: these narrow plants cover little ground at the beginning of their development. Weed regularly around alliums, working shallowly. The fine foliage does not quickly protect the soil from competition. Observe the desired part at harvest: tender stem, aromatic leaves, or mature bulb. For storage bulbs, the harvest stage and drying are as important as the size. Handle the bases with care to limit injuries before cooking or storing. Green onions and storage onions are not harvested at the same stage.

Cooking idea with 'Rossa di Milano' Onion: onion fondue for four servings. Prepare 500g of the harvested part, cleaned and sliced, then sauté in 15ml of olive oil over medium heat. Add 30ml of water, cover, and continue gently until tender. Young shoots cook faster than well-developed bulbs. Stir regularly and add a little water if the bottom sticks. Season with salt and pepper and serve on toast or as an accompaniment to roasted vegetables. Prepare ingredients with clean utensils and adjust the cut to the size of your harvest. This recipe highlights freshly picked parts: remove damaged pieces before preparation. If doubling the quantities, ensure enough space in the dish for even mixing or cooking. Quickly place leftovers in the refrigerator in a sealed container and consume within two days. For a two-person meal, simply divide all quantities by two.
