Alana has an interesting idea of older herbaceous peony roots. I have seen the large, hollow roots filled with what appeared to be soil and just a shell of live material on part of the root. I always wondered why they rotted so quickly and can now understand how the crown utilizes them for food. The new solid roots are attached to the rotted root so I suppose they use the live shell to exchange food back and forth. I will pay more attention the next time I dig.
