This Geophyte (Cryptophyte) forms bulbs as resting buds.

The second clade contains all of the genera that form true bulbs, though Scadoxus is polymorphic for this character.

Potato onions differ from shallots in forming larger bulbs with fewer bulbs per cluster, and having a flattened (onion-like) shape.

Most bulbs are deeply buried, but a few species form bulbs near the soil surface.

It's better to just fertilize them in the fall when they're forming roots and new bulbs.

Some lilies form small bulbs, called bulbils in their leaf axils.

Some bulbous alliums increase by forming little bulbs or "offsets" around the old one, as well as by seed.

As geophytes, they form bulbs with a membranous sheath ("tunic").

The blood lilies came up and formed deep red bulbs, while the pitcher plant developed pitchers filled with liquid that would kill flies.

It forms quite large bulbs (12-15 cm diameter) with a short neck.
