    I am wondering how extensive is the naturalized population of Bladdernut in the Province of B.C. Naturalized meaning has the mother plant, had viable seeds, that have been able to colonize nearby adjoining areas? This plant is not listed as being part of the flora of the Province. Please post a reply
