It is my understanding that all hosta would send up a stalk and bloom and then if the stalk is not removed seeds would develop. The seed would not be true if other hosta were around because of cross pollination and that is how new varieties are formed. I assume once the seeds are mature the pods break open and the seed drops or a person cuts away the stalk in fall clean up. Some plants die after producing seed. I would think that in a warm zone where no winter occurs that the hosta would just continue growing and growing. Am I understanding that a hosta MUST have a cold dormancy in order to LIVE? I could see where a plant would need a dormancy in order to bloom again or produce seed. But hosta will not even live without that cold period? So this means that hosta could not be used as house plants either, even if they were not allowed to make seed?
