Lily seeds or bulbs

Another reason plants in the garden may be clumping rather than 
scattered is that burrowing animals may be discouraged more in the 
garden (I wish I could discourage them a lot more out here!). Plants 
that produce many small offset bulbs are often those that have 
evolved along with heavy bulb predation by burrowing or digging 
animals; the tiny bulblets are not found as easily by the predators 
and can renew the population. Another factor is soil movement: 
bulbous plants that inhabit moving scree or gravelly situations, or 
that grow along swift watercourses (e.g., Lilium pardalinum), are 
likely to reproduce by tiny offsets that are spread as the substrate 
breaks them up and moves them along.
