Why Spring onion is taproot?

Spring onion, also known as scallion or green onion, is not a taproot; it actually consists of a cluster of shallow, fibrous roots. The part of the spring onion that is commonly consumed is the green stalk and the bulb, which is a modified stem. The bulb stores nutrients and energy for the plant, allowing it to thrive, but it does not have the characteristics of a true taproot, which typically grows deep into the soil and serves primarily for anchorage and nutrient absorption. Therefore, while spring onions have a root system, they do not fit the definition of taproot vegetables.
