Cassava is a crop that is grown in the tropics since it requires at least 8 to 18 months of warm and suitable weather to produce a good crop. It does not tolerate freezing temperatures, so it wouldn't be suitable as a crop in Maryland. https://plants.usda.gov/plantguide/pdf/cs_maes.pdf
If you are interested in learning about suitable crops to grow commercially in Maryland, we would encourage you to connect with the Anne Arundel County Extension Office. https://extension.umd.edu/anne-arundel-county/agriculture-natural-resources

Could Cassava be grown in the subtropical United States? As in Florida, Mississippi, Louisiana?
Thanks for your help.
Yes, it is technically possible to grow cassava in subtropical regions of the United States, such as Florida. Here is information from the University of Florida.
