Equisetum hyemale strobilus, at Darłówko on the Baltic Sea coast of Poland. Equisetum hyemale is native to central and northern Eurasia, including Iceland, Greenland, Kamchatka and Japan, where it forms clonal colonies in mesic (reliably moist) habitats, often in heavy clay or sandy soils in riparian zones of rivers and streams where it can withstand occasional flooding, but also in lime ...
The main roots are 6–10 ft (1.8–3.0 m) deep, and the plants send out strong, tough rhizomes, so it forms very strong sod. [4] Depending on soil and moisture conditions, it grows to a height of 1–3 m (3.3–9.8 ft). The stem base turns blue or purple as it matures. Big bluestem blooms in the summer and seeds into the fall.
Equisetum arvense is toxic to stock, particularly horses. [23] It was introduced into New Zealand in the 1920s and was first identified as an invasive species there by Ella Orr Campbell in 1949. [24] It is listed on the National Pest Plant Accord, prohibiting its sale, spread and cultivation. [25]
The deep fibrous root systems of switchgrass left a deep rich layer of organic matter in the soils of the Midwest, making those mollisol soils some of the most productive in the world. By returning switchgrass and other perennial prairie grasses as an agricultural crop, many marginal soils may benefit from increased levels of organic material ...
Equisetum (/ ˌ ɛ k w ɪ ˈ s iː t əm /; horsetail) is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds. [2]Equisetum is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests.
Johnson grass or Johnsongrass, Sorghum halepense, is a plant in the grass family, Poaceae, native to Asia and northern Africa. [1] The plant has been introduced to all continents except Antarctica, and most larger islands and archipelagos. It reproduces by rhizomes and seeds.
It is also known as timothy-grass, meadow cat's-tail or common cat's tail. [3] It is a member of the genus Phleum , consisting of about 15 species of annual and perennial grasses. It is probably named after Timothy Hanson, an American farmer and agriculturalist said to have introduced it from New England to the southern states in the early 18th ...
This perennial bunchgrass is similar to needle-and-thread grass, but it has longer, wider, paler leaves. It can reach over a metre in height. The roots are known to reach 1.8 metres (5.9 feet) deep into the soil. The inflorescence is a panicle of spikelets. Each fruit has a very long, twisted awn, reaching up to 19 centimetres (7.5 inches) in ...
