Canna Lilies. First year trying them but they seem to take dry to submerged. Super easy to find at any big box store. Bloom all summer. These are a leafcutter ant favorite.
I didn't know that cannas would tolerate wet feet.
Mrs. Augie has a ton of the bright red ones in her various flower beds. I think I'll save back a few roots and stick them in the pond bank next spring.
