Which roots are edible

The "eyes" of a potato are buds that can develop into new plants. Tuberous begonias and daylilies are examples of non-edible tubers that can persist for years when cared for correctly.

Water chestnuts, taro, crocuses, crocosmia, gladioli, and jack-in-the-pulpits are corms. A rhizome is a branching horizontal stem growing on or just under the soil surface. Unlike a root, it has nodes. From its' nodes, a rhizome can grow roots, branch to create other plantlets, and send up shoots.

Some plants use thin rhizomes to spread and colonize an area like lily-of-the-valley or Japanese knotweed , while other plants develop thick, fleshy rhizomes that they use both to spread and to store nutrients. Examples of "storage" rhizomes are ginger, turmeric, and irises. Finally, let's take a quick look at one above-ground edible plant structure.
