There are hundreds of types of onions, varying in size and form, as well as sweetness/pungency. They are essential ingredients in cuisines across the globe.
Onions are a cool-weather crop. Because they have require a relatively long growing season, they are usually started from sets, which are simply small onion bulbs. However, the selection of onion varieties available as sets is often limited, so if you want to try unusual varieties you'll have to start them indoors from seed. In general, the stronger-flavored onions keep longer, while mild, sweet varieties are more perishable.
Plant your sets early in the spring -- onions do best if the temperature is cool when they start to grow, and warm as they mature.
