Random plant event: Dahlia 'Munchen' flower

The more time I spend working with all these annuals and perennials, as opposed to tropicals / houseplants, the more pairs of plants I'm running across that I realize now I had confused with one another. Like for example, I thought petunias and pansies were the same thing for a long time. I was even worse about Dahlias, which somehow I had confused with Zinnia. Or at least I think it was Zinnia. Now that I've had a proper introduction to both, it's hard to remember what I thought. Even when I know the difference, sometimes the similarity of the names trips me up: I may never be able to talk quickly and fluidly about Callas or Cannas.
