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.
