There needn't be some genetic doo-dah specific to Lilum tigrinum and its 
parents. It's very common for sterile triploids to resort to vegetative 
propagation. In fact, many commercial clones of bulbs are sterile, selected in 
the wild for their powers of vegetative reproduction and later determined to be 

I have Brodiaea howellii here from its only known site on Vancouver Island. It 
multiplies by stolons with bulbs at the ends and hardly ever flowers. The few 
flowers formed never set seed, which suggests triploid sterility. It's become a 
weed, in fact, having spread from a tiny number of very small bulbs to take 
over an area perhaps a meter square.

I've wondered what would happen if treated with colchicine to create a 
hexaploid. Godzilla? King Kong? Mothra?
