Onions come in different sizes, shapes, colors and flavors, from mild and sweet to hot and strong. A full-grown onion plant has roots, bulbs and leaves. The leaves are long, thin and hollow. They stand straight up and thicken at the bottom to form a bulb.
洋葱有不同大小、形状、颜色，口味从微甜到辛辣。一颗完整的洋葱包括根、鳞茎和叶子。洋葱叶子细长、中空。洋葱垂直生长，并在底部增厚形成鳞茎。

Onions grow best in loose, fertile soil. They can grow in many different climates. In cooler climates, onions may need fourteen to fifteen hours of daylight to start forming bulbs. In warmer climates, onions can begin developing bulbs with fewer hours of daily sun.
洋葱适宜在疏松、肥沃的土壤生长，可以适应多种不同气候。在寒冷气候条件下，洋葱可能需要14-15小时日照才能形成鳞茎。而在温暖气候条件下，洋葱能够在数小时日照的情况下形成鳞茎。
