Brodiaea matsonii has been maintained in cultivation since 1997. I was originally given a single one-gallon pot by Gary Matson which contained about 30 or so corms with leaves present. In growing this plant, its tendency to propagate vegetative became quickly apparent. From the original lot of corms, by the onset of the first summer in cultivation, many young corms had begun to form from offests. Vegetative reproduction is not uncommon in many native California liliaceous endemics: several taxa of Brodiaea do this, others do not.
