From Cookipedia(Redirected from Rhizomes)
In botany, a rhizome is a characteristically horizontal stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. Plants with underground rhizomes include ginger, Western poison-oak, hops, and turmeric. Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species, and ferns, whose spreading stems are rhizomes. Rhizomes may also be referred to as creeping rootstalks, or rootstocks.
