It is hardy to zone (UK) 3. It is in flower from Aug to October, and the seeds ripen from Aug to October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought.
Cultivation:
Easily grown in a well-drained circumneutral or slightly alkaline loamy soil, preferring a warm sunny dry position. Established plants are drought tolerant. Plants are longer lived, more hardy and more aromatic when they are grown in a poor dry soil. This species is closely related to A. sacrorum and often confused with that species. We are not sure if this plant is annual, biennial or perennial, since various reports differ. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – surface sow from late winter to early summer in a greenhouse, making sure that the compost does not dry out[200]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer. Division in spring or autumn. Basal cuttings in late spring. Harvest the young shoots when about10 – 15cm long, pot up in a lightly shaded position in a greenhouse or cold frame and plant them out when well rooted. Very easy.
Edible Uses: …One report says that the plant is edible but gives no more details.

Medicinal Uses:
Hepatic…..The leaf and stem are used in Korea to treat hepatitis, hyperlipaemia and infected cholecystitis. The plant contains flavonoids, sesquiterpenes and other bio-active constituents, though no bio-activites have been recorded scientifically.

Other Uses: The plant yields 1% essential oil, which contains 19% essential oil, 6% camphor

Known Hazards: Although no reports of toxicity have been seen for this species, skin contact with some members of this genus can cause dermatitis or other allergic reactions in some people.

Equisetum variegatum

Botanical Name : Equisetum variegatum
Family: Equisetaceae
Genus: Equisetum
Species: E. variegatum
Kingdom: Plantae
Division: Pteridophyta
Class: Equisetopsida
Order: Equisetales

Common Name : Variegated scouringrush, Alaskan scouringrush, Variegated horsetail or Variegated scouring rush

Habitat : Equisetum variegatum is native to Arctic and temperate regions of Europe, including Britain, N. America, central and northern Asia. It grows on dunes, river banks, wet ground on mountains etc, to 480 metres.

Description:
Equisetum variegatum is a perennial plant. It is a variable species with several ecotypes, some of which are distinct subspecies. The stems can grow to 40 cm (occasionally 80 cm) in height but are often much smaller. Some forms have prostrate stems that creep along the ground while other forms grow more erect. The stems are dark blue-green, slender and rough to the touch. They may be unbranched or have branches growing from the base. The stem nodes are covered with a sheath that is marked with a black band and has dark teeth with white edges. The stems are tipped with a small cone, 3-4 mm across, which is usually green with a black, bluntly-pointed tip.
It is hardy to zone (UK) 2. The seeds ripen from Jul to August.

CLICK & SEE THE PICTURES

Summery : Equisetum species – horsetail family are Creeping, perenial, Branching rootstocks, rooted at the nodes. The Arial stems may be annual or Perennial, are cylindrical, fluted, simple or with whorled branches at the jointed nodes. The internodes are usually hollow. The Surfaces of the stems are covered with Silica. The Cones are terminal.

CLICK & SEE

Leaves and stems:
The sterile stem is green and has no branches. The “leaves” are reduced to a sheath that surrounds the stem. At the top of the sheath is a narrow black band and 3 to 12 teeth that are black/brown with distinct white edges. The teeth persist all season. The stem is evergreen and persists through the winter. The central cavity is ¼ to 1/3 the diameter of the stem….CLICK & SEE

Fruit:
Fertile stems are like the sterile stems but with a ½-inch cone at the tip of the stem. Cones have a sharply pointed tip, mature in late summer or may over-winter and release spores the following spring…..CLICK & SEE

Cultivation:
Prefers a moist but well-drained fertile soil with a pH between 6.5 and 7.5. A very cold-hardy species tolerating temperatures down to about -30°c. Plants have a deep and penetrating root system and can be invasive. If grown in the garden they are best kept in bounds by planting them in a large container which can be sunk into the ground.

Propagation:
Spores – best collected as soon as they are ripe in the spring and surface-sown immediately on a sterile compost. Keep moist and pot up as soon as the plants are large enough to handle. Very difficult. Division. The plants usually spread very freely when well sited and should not really need any assistance.

Medicinal Uses:
Horsetails have an unusual chemistry compared to most other plants. They are rich in silica, contain several alkaloids (including nicotine) and various minerals. Horsetail is very astringent and makes an excellent clotting agent, staunching wounds, stopping nosebleeds and reducing the coughing up of blood. It helps speed the repair of damaged connective tissue, improving its strength and elasticity. The plant has been used in the treatment of sore eyes.

Other Uses:
The stems contain 10% silica and are used for scouring metal and as a fine sandpaper. They can also be used as a polish for brass, hardwood etc. The infused stem is an effective fungicide against mildew, mint rust and blackspot on roses. It also makes a good liquid feed.

Known Hazards : Large quantities of the plant can be toxic. This is because it contains the enzyme thiaminase. a substance that can rob the body of the vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase. The plant also contains equisetic acid – see the notes on medicinal uses for more information.

Notes:
Meadow horsetail is often confused with common horsetail; however, all of meadow horsetail’s shoots are green and have whorls of branches. Only common horsetail has small, brown, unbranched, fertile stems. The sterile stems of meadow horsetail are generally more slender and fragile looking than those of the lengthy of the first branch segment relative to the length of the adjacent stem sheath. The branch segment is shorter than or equal to the stem sheath in meadow horsetail, but longer in common horsetail. Horsetails contain an enzyme (thiaminase) that destroys vitamin B1 (thiamine). In large quantities, they have caused deaths in livestock, though poisoning is quickly reversed by removing horsetails from the diet. Their effect on humans is not completely understood, but raw horsetails can act as a poison. Cooking destroys the thiaminase. Only very small quantities should be taken internally, and people with high blood pressure or other cardiovascular problems are warned against using horsetail.

Cultivation:
Prefers a moist soil with a pH between 6.5 and 7.5. Plants are hardy to about -30°c. Plants have a deep and penetrating root system and can be invasive. If grown in the garden they are best kept in bounds by planting them in a large container which can be sunk into the ground.

Botanical Name : Equisetum hyemale
Family: Equisetaceae
Genus: Equisetum
Species: E. hyemale
Kingdom: Plantae
Division: Pteridophyta
Class: Equisetopsida
Order: Equisetales

Common Name : Dutch Rush, Scouringrush horsetail, Horsetail, Scouring Rush, Rough Horsetai

Habitat : Equisetum hyemale is a native plant throughout the Holarctic Kingdom, found in North America, Europe, and northern Asia. It grows in mesic (reliably moist) habitats, often in sandy or gravelly areas between sea level to 2,530 metres (8,300 ft) in elevation, to 500 metres.

It is primarily found in wetlands, and in riparian zones of rivers and streams where it can withstand seasonal flooding. It is also found around springs and seeps, and can indicate their presence when not flowing. Other habitats include moist forest and woodland openings, lake and pond shores, ditches, and marshes and swamps.

Description:
Equisetum hyemale is a perennial plant, growing to 1 m (3ft 3in).Bloom Color: Unknown. Main Bloom Time: Early spring, Late spring, Mid spring. Equisetum species – horsetail family are Creeping, perenial, Branching rootstocks, rooted at the nodes. The Arial stems may be annual or Perennial, are cylindrical, fluted, simple or with whorled branches at the jointed nodes. The internodes are usually hollow. The Surfaces of the stems are covered with Silica. The Cones are terminal. Form: Spreading or horizontal, Upright or erect, Variable spread.
It is hardy to zone (UK) 5. The seeds ripen from Jul to August.

CLICK & SEE THE PICTURES:

Equisetum hyemale has vertical jointed reed-like stalks of medium to dark green. The hollow stems are up to 3 feet (0.91 m) in height. The stems are not branched with conspicuous ridges, impregnated with silica which makes them feel rough and harsh.

The tiny leaves are joined together around the stem, forming a narrow black-green band or sheath at each joint. Like other ferns and their relatives, the plant reproduces by spores and does not produce flowers or seeds.

The stems are generally deciduous in cold climates, and remain during winter in warmer climates. It forms dense spreading colonies, in full to partial sun.

Subspecies:
Equisetum hyemale subsp. affine — endemic to North America

Cultivation:
Landscape Uses:Container, Ground cover, Woodland garden. Prefers a moist soil with a pH between 6.5 and 7.5. Plants are hardy to about -30°c. The stems of this species were once exported to Britain in quantity from Holland so that they could be used as an abrasive for cleaning pots and pans. Plants have a deep and penetrating root system and can be invasive. If grown in the garden they are best kept in bounds by planting them in a large container which can be sunk into the ground. Special Features:North American native, Invasive, Naturalizing, Wetlands plant.

Propagation:
Spores – best collected as soon as they are ripe in the spring and surface-sown immediately on a sterile compost. Keep moist and pot up as soon as the plants are large enough to handle. Very difficult. Division. The plants usually spread very freely when well sited and should not really need any assistance
Edible Uses:
Strobil (the fertile shoots in spring) – cooked. An asparagus substitute. Caution is advised, see the notes above on toxicity. Roots – dried and then cooked. A source of starch. Caution is advised, see the notes above on toxicity. A further report says that the peeled stems, base of the plant, root and tubers were eaten raw by the N. American Indians, the report went on to say that this may be inadvisable.
Medicinal Uses: 
Antibacterial; Antiinflammatory; Antispasmodic; Appetizer; Cancer; Diaphoretic; Diuretic; Expectorant; Febrifuge; Hypotensive; Parasiticide;
Styptic.

Horsetails have an unusual chemistry compared to most other plants. They are rich in silica, contain several alkaloids (including nicotine) and various minerals. The plant is anticancer, anti-inflammatory, antispasmodic, diaphoretic, diuretic, expectorant, febrifuge, haemostatic, hypotensive and styptic. It also has an appetite-stimulating effect. The barren stems are used, they are most active when fresh but can also be dried and sometimes the ashes of the pant are used. The plant is a useful diuretic when taken internally and is used in the treatment of kidney and bladder problems. A decoction applied externally will stop the bleeding of wounds and promote healing. The plant contains polyphenolic flavonoids with bactericidal activity.

Some Plateau Indian tribes boiled the stalks to produce a drink used as a diuretic and to treat venereal disease. It is used as a homeopathic remedy.
Other Uses:
Dye; Fungicide; Liquid feed; Musical; Paper; Parasiticide; Polish; Sandpaper; Scourer.

The stems are very rich in silica. They are used for scouring and polishing metal and as a fine sandpaper. The stems are first bleached by repeated wetting and drying in the sun. They can also be used as a polish for wooden floors and furniture. The infused stem is an effective fungicide against mildew, mint rust and blackspot on roses. It also makes a good liquid feed. Used as a hair rinse it can eliminate fleas, lice and mites. A light pink dye is obtained from the stem. The hollow stems have been used as whistles. Another report says that the stem joints are pulled apart and used by children to produce a whistling sound.

The rough stems have been used to scour or clean pots, and used as sandpaper.

Boiled and dried Equisetum hyemale is used as traditional polishing material, similar to a fine grit sandpaper, in Japan.

Music :   The stems are used to shape the reeds of reed instruments such as clarinets or saxophones.

Known Hazards :Large quantities of the plant can be toxic. This is because it contains the enzyme thiaminase, a substance that can rob the body of the vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase. The plant also contains equisetic acid – see the notes on medicinal uses for more information.
