Equisetum telmateia

Ecology

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.).
