Field Horsetail

The natural habitats of this deciduous herb include river banks, fixed dune grassland, sea-cliffs and montane flushes, but it has become closely associated with human activity. Being long-lived, vigorous, resistant to herbicides and tolerant of drier conditions than other Equisetum species, it is now frequent on roadsides, railways, paths, soil banks and waste ground, and in quarries and gardens, where its spread is assisted by rhizome fragments. 0?1005 m (Beinn Heasgarnich, Mid Perth).

Shore Horsetail

A vigorous, deciduous herb found in a wide range of habitats, often in the absence of one or both parents. It has been recorded from open woodland and scrub, pond and lake margins, streams and rivers, canals, ditches, roadsides, open peat on moorland, wet pastures and gravel-pits. Many sites are disturbed or seasonally flooded. Lowland.

Water Horsetail

This deciduous herb grows in a wide variety of aquatic and semi-aquatic habitats, from ditches and small ponds to large lakes and sheltered rivers. It tolerates a remarkable range of water and substrate pH, nutrient levels, substrate type and water depth, and is often a pioneer species in freshwater successions. 0-915 m (Breadalbanes, Mid Perth).

Rough Horsetail

A slow-growing, evergreen herb forming colonies of shoots from branching rhizomes. It prefers heavy soils derived from sand or clay which are permanently moist and have a high mineral and silica content. It is usually found in shaded open woodland beside streams and rivers, but also grows in base-rich moorland flushes and sand dunes. 0?610 m (Glen Lyon, Mid Perth).

Mackay`s Horsetail

A rhizomatous evergreen herb found in a range of mostly base-rich habitats, often in the absence of both parents. In Ireland it usually occurs in woodland, and on sheltered wooded riverbanks and lake margins. In Britain it grows in dune-slacks, on flushed sandy riverbanks, and in peaty turf in coastal machair. It is sterile and spreads by rooting stem and rhizome fragments. Lowland.

Marsh Horsetail

A deciduous herb associated with marshes, damp pastures, ditches, dune-slacks, streams, rivers and mountain flushes. It tolerates a wide range of soil types and substrates, provided that they are permanently damp and adequately base-rich. 0-945 m (Meall nan Tarmachan, Mid Perth).

Shady Horsetail

An evergreen herb, typically found on sloping sites where the substrate is derived from calcareous alluvial silts or sand, especially lightly wooded stream banks in the lower parts of upland valleys. It can also extend onto open moorland, and is found on grassy slopes beneath base-rich upland cliffs. 0-915 m (Breadalbanes, Mid Perth).

Branched Horsetail

An erect evergreen herb found growing in rough grassland near the sea, on sand or clay soil. Lowland.

Wood Horsetail

A deciduous, colony-forming herb which generally grows on deep, mildly acidic, often peaty soils that are kept permanently damp by flushing. It occurs on the lower slopes of mountain valleys, steep streamsides, wet ledges and open flushes, beside lakes and on the edges of drainage ditches. It also occurs on wet road verges and railway embankments. 0-850 m (Breadalbanes, Mid Perth).

Great Horsetail

A robust, deciduous, colony-forming herb of base-rich clay soils in sites with spring-lines, permanent seepages and open flushes, especially in areas where porous rocks are interbedded with clays. It prefers open habitats and is particularly frequent on eroding sea- and river-cliffs, but also grows on roadsides and railway embankments. Lowland to 365 m in Fossdale (N.W. Yorks.).
