Bulbs 1–3+, variable, some with poorly developed bulbs, others ovoid with 1–2 large bulbs and several yellowish to light brown bulbels at base, 0.4–1(–3) × 0.4–1(–1.5) cm; outer coat enclosing 1 or more bulbs, yellowish, membranous; inner coats white to light brown, cells not evident, fibers ± parallel, few.

Discussion
Normally the umbel of Allium ampeloprasum has no bulbils, but there are some variants with a few flowers that produce bulbils. The species has been reported as established in New England and adjacent Canada and can be found along roadsides and in other disturbed areas. It is probably conspecific with A. porrum Linnaeus, the leek of commerce. Allium porrum can be distinguished from A. ampeloprasum based on its unique bulb morphology and chemistry from centuries of cultivation and selection.
