The Q&A Archives: Canna Yellow Mottle Virus

Question: Have Canna Lilies from your nursery been found having Canna Yellow Mottle Virus?

A few days ago, I bought a Pretoria Canna Lily from Rogers Gardens. The plant had some leaves with burned edges and snail bites. I bought it anyway believing those are things I can fix. Today, I did a research about it and became aware of the Canna Yellow Mottle Virus. I am wondering if your nursery has any information about the Virus?

Answer: Canna collections worldwide have experienced problems with virused plants. In the United States the Canna Yellow Mottle Virus has swept rapidly through collections and nurseries across the county. In an effort to curb further spread of this virus, the California Department of Agriculture has ordered the destruction of any infected variety. Inspectors from the Agricultural Commissioner's office for each county has been inspecting and sending in for analysis every variety of Canna from California nurseries. We have had our inspection and then destroyed all virused plants; the canna we continue to list are all virus free and we will continue to monitor and test these plants to insure this.

Canna yellow mottle virus (CaYMV) causes distortion, stunting and chlorotic streaks in the leaves. Streaking is the most commonly recognized symptom of this virus; as long as the leaves on your plant remain streak-free, you won't have to worry about your canna having yellow mottle virus.
