Plants with underground rhizomes include [[ginger]], [[hops]], and [[turmeric]], significant for their medicinal properties, and the weeds [[Johnson grass]], [[bermuda grass]], and [[Cyperus rotundus|purple nut sedge]]. Some plants have rhizomes that grow above ground or that sit at the soil surface, including some ''[[Iris (plant)|Iris]]'' species, and [[fern]]s, whose spreading stems are rhizomes. Rhizomes may also be referred to as creeping rootstalks, or rootstocks. A [[stolon]] is similar to a rhizome, but, unlike a rhizome, which is the main stem of the plant, a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, e.g., the [[strawberry]] plant. In general, rhizomes have short internodes; they send out roots from the bottom of the nodes and new upward-growing shoots from the top of the nodes. For many plants, the rhizome is used by gardeners to propagate the plants by a process known as [[vegetative reproduction]]. Examples of plants that are propagated this way include [[asparagus]], [[ginger]], [[iris (plant)|iris]]es, [[Lily of the Valley]], [[Canna (plant)|Cannas]], and [[sympodial]] [[orchid]]s. A stem [[tuber]] is a thickened part of a rhizome or [[stolon]] that has been enlarged for use as a [[storage organ]]. <ref>Kingsley R. Stern ''Introductory Plant Biology'', 10th ed. ISBN 0072909412</ref> In general, a tuber is high in [[starch]], for example, the common [[potato]], which is a modified stolon. The term tuber is often used imprecisely, and is sometimes applied to plants with rhizomes. The rhizome is a key metaphor in the [[philosophy]] of [[Gilles Deleuze]] and [[Felix Guattari]]. ==References== <references/> [[Category:Plant anatomy]] [[Category:Plant reproduction]] [[ca:Rizoma]] [[cs:Oddenek]] [[da:Rhizom (botanik)]] [[de:Rhizom]] [[et:Risoom]] [[es:Rizoma (botánica)]] [[eo:Rizomo]] [[fr:Rhizome]] [[id:Rizoma]] [[it:Rizoma]] [[he:קנה שורש]] [[lt:Šakniastiebis]] [[hu:Gyöktörzs]] [[nl:Wortelstok]] [[ja:地下茎]] [[pl:Kłącze]] [[pt:Rizoma]] [[ro:Rizom]] [[sl:Korenika]] [[sr:Ризом]] [[fi:Maavarsi]] [[vi:Thân rễ]] [[uk:Кореневище]]
