It doesn't surprise me either there exist perennial Daturas with a swollen root but I never have seen one. The D. wrightii mentioned in the references will not survive the wet winters here. When I tried to grow it in containers I couldn't find any large or swollen tuber in the container during winter. Also survival rate was very low. Much easier to grow from seed and treat as an annual. Still would like to see a picture of such a swollen root out of curiosity what I have missed on my plants.
