I have purchased two different types of dahlias this year. They are my first ones and I'm excited to see them pop out of the ground! I hope they all survive. I don't remember what they're called, but three are yellow dinner plate dahlias and three are smaller but equally gorgeous fuchsia dahlias.
Here are some links to some great dahlia information:
