While doing a search to confirm the ID we found a post on this forum, we read it and others. A couple asked about Stuttgart and one about cannas in ponds and planting media so we decided to post.

We bought this plant in a gallon pot with pea gravel and put it in the pond on a shelf a foot down with the top of the pot about 4" under water. We have another type of canna planted the same way. It is pink flowers behind Bernie at the other end of the pond. It is a smaller variaty and hasn't got as tall. Both were sold as pond plants so we don't know if this works with all varieties.

We live in an area where only the surface of the pond freezes and we leave them in the pond over winter. We just cut off the stalks near the water after the tops die from frost or freezing. At this time you can no longer see the pots. The rhizome is a large mass around the pot just in the water.

The pond level is just below the top of the wall and the bottom of the pot is just above Bernie's feet. The plant is 10' tall from the top of the pot.

I was reading up on container water gardening last night and cannas were one of the plants I see a lot of people using in container water gardens. So, if you have a whiskey barrel half that you can line with plastic I think you have everything you need to grow cannas in a pond. From what I read they should generally be planted 0-6" down in the water, not at the bottom of the container.

I grow my florence vaughns& Bengal Tiger in the my pond last yr.(I place rocks in bottom of pot and set rizomes on rock to adjust the hight)They sure didn't get that tall though..lolNice work.
