Pteris vittata is native and widespread in the paleotropics: found from the east, to the south tropical, and southern Africa (in Angola; Kenya; Lesotho; Malawi; Mozambique; Namibia; Tanzania (including the Zanzibar Archipelago); Cape Province, Free State, KwaZulu-Natal, and Transvaal in South Africa; Eswatini; Uganda; Zambia; and Zimbabwe); temperate and tropical Asia (in the provinces of ...
“Roots need to be just underneath the surface of the soil,” said Sharon Yiesla, plant knowledge specialist in the Plant Clinic at The Morton Arboretum in Lisle.
The plants often grow together in crowded colonies and spread by runners at or just under the soil surface. In late summer the plants produce tubers that are twice as long as wide, [9] each typically measuring 0.5 to 5 cm (1 ⁄ 4 to 2 in) in diameter. [8] The plant produces rosettes of leaves and an inflorescence on a long rigid scape.
Andropogon gayanus seeds. This tufting perennial bunchgrass can grow 4 m (13 ft) tall and 70 cm (2.3 ft) in diameter, and has hairy leaves. Most of its roots are fibrous, [2] spreading close to the surface of the soil for up to 1 m (3 ft 3 in), [3] but it also has thick cord roots which store starch and anchor the plant as well as vertical roots able to extract water from a greater depth ...
Artemisia douglasiana is used by Native American tribes as a medicinal plant to relieve joint pain and headaches, and to treat abrasions and rashes (including poison ivy). It is also used to treat women's reproductive issues, including irregular menstruation and is occasionally used as an abortifacient .
The correct environment of air, mineral nutrients and water directs plant roots to grow in any direction to meet the plant's needs. Roots will shy or shrink away from dry [22] or other poor soil conditions. Gravitropism directs roots to grow downward at germination, the growth mechanism of plants that also causes the shoot to grow upward. [23]
Mesquite is a common name for some plants in the genus Prosopis and Neltuma, both of which contain over 40 species of small leguminous trees. They are native to dry areas in the Americas. They have extremely long roots to seek water from very far under ground. As a legume, mesquites are one of the few sources of fixed nitrogen in the desert ...
A highly variable plant, taking many forms, E. guttata is a species complex in that there is room to treat some of its forms as different species by some definitions. [9] The plant ranges from 10 to 80 centimetres (4 to 31 + 1 ⁄ 2 in) tall with disproportionately large, 2 to 4 cm long, tubular flowers. The perennial form spreads with stolons ...
