What kind of plant is this? (UPDATE: It's a Canna Lilly. Thanks @danim24 and @adlibcorner!) We're in Zone 7 in the Dallas area. I think I had some of these at our old house and they shrivel up and die during the winter months, but being bulbs, come back strong in the spring. Thing is, I don't want to have this tub empty in the winter waiting for that to happen. What do you recommend? There is a bamboo plant behind it, so don't let the smaller leaves confuse you. Refer to the close up of the flower itself, too! Note the well and pergola swing this dad made for his bride in the background of the close up shot!
