Collection of 4 colourful onions

<p style="text-align: justify"><span class="attr"><strong>The <a href="https://en.promessedefleurs.eu/vegetable-gardens/vegetables-by-variety/onions.html" target="_blank" rel="noopener">onion</a></strong> is a root vegetable from the <strong>Liliaceae</strong> family, which includes many edible and aromatic plants such as <a href="https://www.promessedefleurs.com/conseil-plantes-jardin/fichefamille/ail-planter-cultiver-recolter/" target="_blank" rel="noopener">garlic</a>, shallots, leeks, and chives. The onion is cultivated both as a <strong>vegetable</strong> and as a <strong>condiment</strong>, <strong>with its bulb being the most commonly consumed part, though its leaves and stems are also used, much like chives.</strong></span></p> <p style="text-align: justify"><span class="attr">Onions are typically classified into two categories: <strong>spring onions and storage onions (also known as “keeping onions”)</strong>. The former are harvested with their fresh leaves and consumed whole. These are often white onion varieties such as the <strong>‘Blanc Printanier Parisien’</strong> and the <strong>‘Rouge de Florence’</strong>, both of which have a mild flesh, making them excellent for salads and raw dishes. </span><span class="attr">Storage onions can also be harvested fresh, but more often they are harvested dry at full ripeness. Among these, I particularly like the <strong>‘Stuttgart’</strong> onion, which produces large yellow bulbs that store well. As a proud Finistère native, I must recommend the ‘Johnnies’ onion—the <strong>‘Rosé de Roscoff’</strong> variety even benefits from an AOC (Protected Designation of Origin) in Haut-Léon. It’s a marvel that, when raw, develops fruity aromas with a mild sharpness and a juicy, crunchy texture. When cooked, its texture becomes meltingly tender, and its sweet flavour dominates. Generally speaking, <strong>varietal choice is very important</strong>, with over 1000 varieties listed in the European catalogue. What’s particularly interesting is that there are many local varieties in France, each adapted to different terroirs. That’s why I encourage you to seek out and grow varieties from your own region.<br /> </span></p> <p style="text-align: justify">Growing onions requires a <strong>sunny position</strong> and <strong>light soil</strong>, sufficiently <strong>well-drained</strong> and <strong>fertile</strong> but <strong>without fresh manure</strong>. Depending on the variety, onions can be sown in spring or autumn, or planted from bulblets, most often in spring. Maintenance during cultivation involves regular weeding and hoeing, as well as keeping an eye out for a fairly common pest: <strong>the onion fly</strong>.</p> <div id="attachment_45162" style="width: 1210px" class="wp-caption aligncenter"><img aria-describedby="caption-attachment-45162" loading="lazy" decoding="async" class="size-full wp-image-45162" src="https://www.promessedefleurs.com/blogwp/wp-content/uploads/2018/06/oignon-rouge.jpg" alt="Red onions" width="1200" height="826" /><p id="caption-attachment-45162" class="wp-caption-text">Red onions</p></div> <p> </p>
