What does bulbil mean?
A bulbil is a small, bulb-like bud that some plants produce as a means of asexual reproduction. Unlike a true bulb, which is an underground storage organ, a bulbil typically forms above ground — most often in the axil where a leaf joins the stem, though it may also appear in place of flowers. Plants as familiar as tiger lilies and various onions and garlics commonly produce them; when a bulbil matures, it drops off or is collected and can grow directly into a new plant genetically identical to its parent. The term belongs mainly to botany and horticulture, appearing in seed catalogues, gardening guides, and botanical descriptions rather than casual speech. For gardeners, bulbils are prized as an easy, reliable way to propagate favourite plants without sowing seeds, and they offer a striking example of how some species bypass sexual reproduction altogether.
nounA small bulb, or bulb-like bud, that forms in the axil of a leaf or in place of a flower, serving as a means of asexual reproduction in plants such as lilies and garlic.
- A small, bulb-like vegetative bud produced by certain plants (e.g. lilies, onions, garlic) in a leaf axil or inflorescence, which can detach and develop into a new plant.
"The tiger lily produces tiny black bulbils along its stem, each one capable of growing into a new plant."
"Gardeners often harvest the bulbils that form where the tiger lily's leaves meet the stem and pot them up to raise new plants."
"In hardneck garlic, the scapes curl at the top and produce clusters of small bulbils instead of true seeds."
Regular plural; countable noun referring to multiple such buds, usually discussed in the context of harvesting or propagation.
"She collected dozens of bulbils from the garlic scapes to plant next season."
Tiger lilies skip seeds entirely — they grow ready-made baby plants called bulbils right on their stems.

Etymology of bulbil
Bulbil derives from the Latin 'bulbus', meaning bulb or onion, which itself traces back through Greek 'bolbos'. The diminutive form reflects the word's sense of a miniature bulb. It entered English in the early modern period, borrowed via French, alongside related terms such as 'bulblet' and 'bulbous', all sharing the same classical root for onion-like underground organs.

How bulbil is actually used
Bulbil is a technical term used chiefly in botany, horticulture, and gardening writing; it is uncommon in everyday conversation. It refers specifically to asexual propagative structures, so it appears mostly in contexts discussing plant reproduction and cultivation.
Easily confused with bulbil
A bulb is the full underground storage organ of a plant, whereas a bulbil is a much smaller, aerial or above-ground bulb-like structure used for propagation.
