There is some conflicting information regarding spinosissimas and I don't know which is correct. A reason given for their wide distribution was that they grew from cuttings easily and early settlers took them with them when they left the eastern coast and traveled west. However some modern authorities such as Mel Hulse state that they are very difficult to impossible to grow from cuttings. Peter Boyd who has wide experience with them believes they can be propagated in winter or early spring. Which is correct? If they can be propagated by cuttings which is the best way to do so?
