The word onion comes from the Latin word unio for "single," or "one," because the onion plant produces a single bulb, unlike its cousin, the garlic, that produces many small bulbs. The name also describes the union (also from unio) of the many separate, concentrically arranged layers of the onion. We grow several different varieties of onions, including Walla Walla, yellow, and red.
Store in a cool, dry, well ventilated place, in single layers. If the onions at home show signs of sprouting, cut away the sprouts and use them immediately. Use fresh onions (like Walla Walla) within a week.
