pring onions are comprised of small round to oval bulbs, averaging 2 to 5 centimeters in diameter, attached to a straight, layered stalk of overlapping leaves. The bulbs are smooth, firm, crisp, and succulent, found in bright white to red hues, depending on the variety. There may also be a cluster of fresh, flexible, and fine tan roots attached to the bulb's base. The slender, tubular leaves have a stiff, thick, and crunchy consistency and are hollow, bearing dark green hues on the edges and lightening to a pale green tone near the bulb. Spring onion bulbs contain sugars and are absent of the gases developed in more mature bulbs, creating a sweet and mild, mellow flavor. The leaves have a stronger taste and contribute herbaceous, pungent, and grassy nuances.Spring onions contain vitamin A to maintain healthy organ functioning, vitamin C to strengthen the immune system, and vitamin K to promote faster wound healing. The onions also provide calcium to protect bones and teeth, potassium to balance fluid levels within the body, antioxidants to reduce inflammation, and other nutrients, including phosphorus, magnesium, and copper.
