It is Dahlia.
How does your garden grow today? : )
My Sedum lydium is growing well this year. Last year the tiny little piece I had just sat their. Though I was goint to lose it. This spring it took off so fast I couldn't believe it. I will have to get a current photo, this one is from May 2011. I can't believe how much it's grown since may.
Here it is from last Nov 2010
