It sounds like you may have purchased the Canna cultivar called ‘Cleopatra’, or a similar cultivar. The two different colored flowers on the same plant are caused by a mutation in the growing point of the plant. Sometimes the mutated cells form the flower, and sometimes the normal cells form the flower. I have read that the origional color is red, and the yellow is the mutation. What an interesting plant.

I hope it grows well for you.

After the first fall frost kills the Canna foliage, dig the plants out of the ground. Cut the foliage off. Place the rhizomes in crates and cover them with peatmoss. Place them in a cool dark area that does not freeze. A heated garage or basement will work. The rhizomes should feel firm. If they rhizomes dry out too much, they will start to feel softer or brittle. If they appear to be getting too dry, add some water. Too much water may cause fungal issues. Two weeks before the last frost in the spring, plant them back in the ground. If you have a sun porch with cool temperatures, you can put them in a pot and grow them inside. I hope that helps. Alan

I am glad you like our gardens! We are not a mail order company. Hopefully you will be able to buy Longwood Cannas at your local garden center one day. Several companies produce Cannas from seed in cluding Takii and Park Seed. You may want to look at what those companies offer. Karchesky Cannas sells plants and carries a wide variety of cultivars. Happy Gardening

I remember out walk through the Canna fields too. Thanks for all of your hard work with Cannas! You have an impressive collection.

I agree, we all have to be on the look out for plants that have contracted viruses and keep them away from clean plants.

I hope you can visit one day soon.

We have worked very hard to eliminate disease, also. Unfortunately, we don’t have the facilities that you do, but we have also done well nonetheless.

I do worry about all the diseased cannas still being put out. It does not take long to pass through a collection. So long as that is still happening, healthy cannas will always be in jeopardy. So those growers need to work harder, too.

Thanks for posting this. It is great to see

Hopefully, I will be able to visit you on day again. And you are always welcome here, too.

Thanks for your comment. I am sorry to hear about your Canna collection. Don’t give up hope. There are some good seed varieties of Canna on the market. I continue my virus elimiation efforts in tissue culture as well.
