Last Dahlias

I know this pictures is kind of blurry but there aren't any more dahlias in the patch so this is it for the year. I picked these just before the first really hard frost killed the plants. We've been enjoying them inside for several days now. I leave the tubers in the ground covered by a heavy mulch of hay, leaves, grass clippings, sawdust, whatever I can find and it works most years. If it doesn't I get to indulge myself in selecting new ones. There are so many gorgeous ones out there and I never get to grow them all.
