Canna lily replanted

Question

This is the third year I pulled up the Canna roots and bulbs and replanted in the spring. Originally the where different colors. They all have morphed into a rosy orange color with very small petals. They no longer look like different colored irises. I wonder why.

Answer 1

They definitely won't turn into an iris, but they can revert colors, especially in unstable lines. This can also be explained by competition. One color can outcompete, and kill off other colors. This is the most likely scenario. This happens fairly often.

The best thing to do will be to only plant like types with like, and keep them in separate beds that cannot be accessed by one another to prevent this in the future.
