I am finding long bulb type roots in a bed where canteberry bells and campanella have been grown. Could these be for these flowers?

These are usually propagated by seed. Can you send in a photo? This can help me to determine what this could be.
Canterbury bells is a biennial meaning it dies after flowering. Campanula has fleshy roots that spread in every direction, but no bulb. Can you post a picture?
