I'm surprised there isn't a Dahlia forum here, but I have always thought of them among tender summer bulbs- their tuberous roots are certainly bulb like in many ways.. These Dahlias have overwintered in the ground the last 3 years. I gave them a little extra attention this year, and they've produced some of the largest blooms I've ever grown. They sure make late summer sparkle!
"...and don't think the garden loses its ecstasy in winter. It's quiet, but the roots are down there riotous." Rumi
