Bottom one shows a seed pod.
I think these plants are interesting. We moved some dirt from the front yard (after we'd lived here about three years) and these cannas came up from it. I don't know how or why they were lying dormant or why they decided to grow after we bothered them, but I'm awfully glad they did.
DH's grandmother lived here before us, so they must have been hers. I like that connection to her.
