Along with other frost-prep harvesting, it was time to dig up the Dahlia plants and take a gander at the roots. The plants did very well, with stems almost 2 inches thick. The roots were like small-medium sweet potatoes.
The white, thin-skinned roots are this year’s growth. As they age, they’ll get a thicker skin, which needs peeling if one is going to eat them.
These are properly roots, not tubers, since the storage roots do not have buds and can’t be called a rhizome (an underground stem); a tuber is a swollen storage rhizome, like a potato.
