An antique spurge plant, Euphorbia antiquorum, sending out white rhizomes. In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and ...
The plant grows from a thick rhizome, typically measuring 30 cm (0.98 ft). It has leaves that are large, each 40–55 cm (16–22 in) long and 30–40 cm (12–16 in) wide. Blooming early in the spring, just its blossoms can be seen above the mud. The plant is generally pulled back into the earth as it develops every year.
The rhizomes are sensitive to frost and will rot if left unprotected in freezing conditions. In areas with winter temperatures below −10 °C (14 °F) in the winter (< USDA Zone 8b), the rhizomes can be dug up before freezing and stored (above 7 °C or 45 °F) for replanting in the spring.
Goldenseal reproduces both clonally through the rhizome [3] and sexually, with clonal division more frequent than asexual reproduction. It takes between 4 and 5 years for a plant to reach sexual maturity, i.e. the point at which it produces flowers.
Turmeric (/ ˈ t ɜːr m ər ɪ k, ˈ tj uː-/), [2] [3] or Curcuma longa (/ ˈ k ɜːr k j ʊ m ə ˈ l ɒ ŋ ɡ ə /), [4] [5] is a flowering plant in the ginger family Zingiberaceae.It is a perennial, rhizomatous, herbaceous plant native to the Indian subcontinent and Southeast Asia that requires temperatures between 20 and 30 °C (68 and 86 °F) and high annual rainfall to thrive.
The rhizome branch produced each year is usually very weak and dies the next, but serves as a reserve rhizome apex, with the potential to become a new main rhizome. [14] This happens if the plant is especially productive, or more frequently if the tip of the main rhizome is damaged so that it cannot grow.
The rhizome is creeping and the fronds appear to have random placement, originating at various points. The rhizome appears reddish-brown, and has a sweet licorice flavor. Since it is a fern, P. glycyrrhiza reproduces by spores; the spores form in two rows of sori , which look like large spots on the undersides of the leaves.
The plants produce several stems from a creeping underground rhizome; some stems bear a single leaf and do not produce any flower or fruit, while flowering stems produce a pair or more leaves with 1–8 flowers in the axil between the apical leaves. The flowers are white, yellow or red, 2–6 cm (1–2 in) diameter with 6–9 petals, and mature ...
