The dahlia flowers and tubers are edible, but I recommend growing them for their beauty instead.

The Sublime World of Dahlias
Zone | In 8-11 zones, dahlias can grow and overwinter in your garden. Fortunately for the rest of us in zones 2-7, we can still grow dahlias, but we have to winterize them every year. This means digging up the tubers and keeping them safe until the temperature is appropriate for planting again.

There is much more to learn about the history of the sublime world of dahlias and their care, but don’t let that stop you from growing your own. They are not as elusive as one might think. The beauty dahlias can bring to your garden and as cut flowers will be a wonderful reward for taking the jump.
