Yes the plants are canna lily. They grow from rhizomes (type of bulb) underground and spread easily especially in wet areas. Some kinds can be planted from seed as well.
I grow some in my pond sometimes. They also come in red, or green and yellow striped foilage etc so they look pretty even without the flowers. They are related to bananas so should not be toxic or anything. Some of the banana plants in Louisiana (the Bordelon banana that practically grows wild there..has reddish underleaves) should be okay to plant in with them as well and easy to find.
Great pics of pens. I have been researching how to make pens and what I could put in there so I can get some peafowl soon.
