Onions can also be grown for their green immature stems or they may be able to be grown for their mature bulbs. The ones strong-smelling crops have been very talked-about for centuries.
Nowadays there are two main kinds of onions which will also be grown in the home garden: the more youthful, green or white, bunching types eaten recent and previous than the mature bulb has formed, and people who expand a large, coated bulb with a papery pores and pores and skin that is most ceaselessly eaten boiled or fried (and as well as eaten recent although some are beautiful solid).
Onions grown for their green stems are sometimes called green onions, spring onions, and scallions. (The words are ceaselessly used interchangeably.)
