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 ...
A rhizome is a horizontal stem that often grows underground, usually sending out roots and shoots from its nodes. Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species. Usually, rhizomes have short internodes; they send out roots from the bottom of the nodes and new upward-growing shoots ...
Roots may be spread along the rhizome, clumped at the nodes, or clumped near the base of leafy shoots. The rhizome is the perennial part of the plant and growth is by branching of the rhizome. Flowering/fruiting shoots are attached to the rhizome by a discreet internode, are short-lived and wither at the end of the growing season. [6] Stems and ...
Aspidistra elatior, the "cast-iron plant", is a popular houseplant, surviving shade, cool conditions and neglect. It is one of several species of Aspidistra that can be grown successfully outdoors in shade in temperate climates, where they will generally cope with temperatures down to −5 °C (23 °F), being killed by frosts of −5 to −10 ...
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 ...
Rhizobacteria are root-associated bacteria that can have a detrimental (parasitic varieties), neutral or beneficial effect on plant growth. The name comes from the Greek rhiza, meaning root. The term usually refers to bacteria that form symbiotic relationships with many plants . Rhizobacteria are often referred to as plant growth-promoting ...
The labellum is white, circular, with a length of 6–7 millimeters and width of 3–4 millimeters, the tip 3 cracks, the base pastes the tight pistil column full terminal, has a pair of pulp callus, in the callus connection perianth tube. The pistil column length 5–7 millimeters, have the short pistil column foot. [3]
Reynoutria sachalinensis is a herbaceous perennial plant growing to 2–4 m (79–157 in) tall, with strong, extensively spreading rhizomes forming large clonal colonies. The leaves are some of the largest in the family, up to 15–40 cm (6–15.5 in) long and 10–28 cm (4–11 in) broad, nearly heart-shaped, with a somewhat wavy, crenate margin.
