Description: Onions are the backbone to nearly any savory dish acting with such humility that they are often overlooked in the garden. While easy to grow from seed, the key is selecting the right type for the region. Long day onions tend to grow best in the North, when the longer days of summer trigger bulbing. Short day onions tend to grow best overwintered in the South when the shorter days of spring are enough to promote bulbing. Intermediate day onions fall more or less in the middle. And take heart! If all else fails, any onion can be pulled and eaten as a scallion. Nutrients: dietary fiber, vitamins C, B6, folate, manganese and calcium.
