My Chilean native plants for the garden book mentions propagating 
this species only from seed, not from root cuttings. In nature one 
sees this species as a single clumping plant or as a colony, but I 
don't know if the colonies are formed by seed or stolons. Seedlings 
should be noticeably smaller than the parent plant, which when mature 
can have a stalk up to 2 meters tall or even more. However, when I 
grew it in the Pacific Northwest, it never got that tall.
