Careful with this one! Please grow in containers if you must, and remove seed heads before maturity. This plant is highly invasive in most of the US. The leaves are extremely prickly, making it even more difficult to remove from wild areas. I worked for the National Park Service one season removing this plant from our national parks in California. Very difficult to eradicate and not fun to handle. The patterning of the leaves is pretty, but it's just not worth the risk.
