Horsetail—primeval plant that is high in silica; tops are very similar to and may be eaten like asparagus. Lamb's quarters—leaves and shoots, raw, also prevents erosion, also distracts leaf miners from nearby crops. Nettle—young leaves collected before flowering used as a tea or spinach substitute. Plants have use as compost material or ...
Equisetum arvense, the field horsetail or common horsetail, is an herbaceous perennial plant in the Equisetidae (horsetails) sub-class, native throughout the arctic and temperate regions of the Northern Hemisphere. It has separate sterile non-reproductive and fertile spore-bearing stems growing from a perennial underground rhizomatous stem system.
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.
The plants have intercalary meristems in each segment of the stem and rhizome that grow as the plant gets taller. This contrasts with most seed plants, which grow from an apical meristem - i.e. new growth comes only from growing tips (and widening of stems). Horsetails bear cones (technically strobili, sing. strobilus) at the tips of some stems.
Equisetum laevigatum is a species of horsetail in the family Equisetaceae. [2] [3] It is known by the common names smooth horsetail [4] and smooth scouring rush. This plant is native to much of North America except for northern Canada and southern Mexico. It is usually found in moist areas in sandy and gravelly substrates. It may be annual or ...
"Leave the leaves, brush, and stems in place over the winter because birds eat the seed heads, pull the stems and twigs for shelter, and many of our beneficial pollinators, like solitary bees ...
Equisetum palustre, the marsh horsetail, [2] is a perennial herbaceous pteridophyte belonging to the subclass of horsetails (Equisetidae). It is widespread in cooler regions of Eurasia and North America .
The side branches are slender, dark green, and have 1–8 nodes with a whorl of five scale leaves at each node. [citation needed] The water horsetail has one of the largest central hollow of the horsetails, with 80% of the stem diameter typically being hollow. [3] Equisetum fluviatile – a broken stem with the central hollow exposed.
