Cassava grows well in Central Florida were we live. Although it is readily available at the grocery stores around us, most of the time it has been sprayed with a shiny wax material, so roots bought at the store will not grow.
Thankfully, there are plenty of people growing cassava in Florida, so either you get some from a friend or buy some on eBay. I bought organic cuttings from a seller ( in Ft. Myers because I can grow the plants in our small greenhouse and have them ready to plant in March after the ground warms up again.
I think the plant itself is very nice, looks quite ornamental/decorative, so it could even be grown as edible landscaping in a subdivisions property with strict rules about keeping ornamentals only. It also has an interesting use that my eBay seller pointed out on his item description:
"TROPICAL JUNGLE: One cassava plant can block the view from a neighbor you don't want to see. The picture (above) in a 70 gallon pot is doing just that."
My favorite way of eating "yuca" is fried with a cilantro/tomatillo dip. You first have to boil it until soft before frying. It is also good boiled with olive oil or butter and chopped parsley over it. In college I had a friend from India who would boil it, then sautee mustard seeds and pour them over it - delicious!
