Growing Spider Mums in Florida

Growing Spider Mums in Florida

I am having a heck of a time Googling places that sell spider mums to plant. Are they seeds or bulbs? I found a lot of places that sell the cut flowers, but I want a plant to grow. A potted plant is fine, just something I can put in my garden. Am I not saying the name right? There are a lot of chrysanthemums out there, but I wanted this type in particular, which I had always heard as a "spider mum". I am also having trouble finding info on if they will even grow in Florida (I think I am right on the 9a/9b border.) I read that they liked a lot of sunlight, which I defiently have. I also can't find when to plant them. I'm assuming sping/summer, since that's when I see them in bouquets in stores. Thanks!
