Bolgewas is a term used in Dutch horticulture to describe crops that form an underground storage organ in the form of a bulb. In practice, it refers primarily to edible bulb crops, especially species in the Allium genus such as onion (Allium cepa), garlic (Allium sativum) and shallot (Allium cepa var. aggregatum). These bulbs store nutrients and serve as a means of asexual propagation. They differ from tuber crops (like potato) and from other root vegetables in the anatomy of the storage organ: onions consist of fleshy leaves arranged in layers, while garlic develops a bulb made of individual cloves.
Botany and propagation methods are distinctive for bolgewas. Onions and shallots can be grown from seeds or
Harvesting and storage follow bulb maturity. Onions and shallots are typically lifted when tops begin to yellow
Bolgewas crops are of major importance worldwide for food production, culinary use, and agricultural livelihoods, with
