By vegetative means, probably the formation of daughter bulbs.

AFAIK (as far as I know) this is a fairly common scenario among geophytes.

Brodiaea howellii (which has some other name now) occurs only at one site on 
Vancouver Island, according to my botanical friends. I collected a few tiny 
bulbs from that site many years ago and (foolishly, as it happened) planted 
them in a raised bulb bed.

Over the years, very few flower stems have formed, none have set seed, but 
underground the soil is filled for several feet in all directions with offsets 
formed at the ends of stolons or rhizomes.

No DNA analysis to confirm my suspicion, but the behavior strongly suggests 
I've got a sterile triploid form.
